Welcome to ALLERTON!  Firstly, we’d like to thank you for choosing us for your upcoming project, we do not take the faith that you have placed in us lightly and from here on, we’ll do everything that we can to exceed your expectations. We’re very much looking forward to working with you!

Before we can start any work on your project, we need to get the boring stuff out of way first and yes, you’ve guessed it, we’ll need your signature.  You can complete and sign this document online, there is no need to print and post it back to us.

This document should be read together with the We Do/ You Do information leaflet which we will send to you if you are interested us working with you.  The We Do/ You Do contains all sorts of useful information about what to expect during the works and we would encourage you to read this carefully.

1. Preparing your property for our technicians

The majority of the information that you need to prepare for our arrival is contained in the We Do/ You Do leaflet.

Though we will make every effort to ensure that your project runs as smoothly and efficiently as possible, we find that the best projects are those where we and our clients work together as one team. We’re always on hand to talk to and we would encourage you to ensure that you (or someone you nominate) are contactable throughout the project too. If you have any questions, you should contact your Project Manager or, if they are not available, our Customer Services Team on 0330 111 3377.

2. Gas, electricity and water

Due to the heavy nature of some of our works, damage to services may be unavoidable, even when taking the extra care that we do. We will cover the cost of repairing what damage is caused to cables/pipework, but where pipes, cables, installations or similar do not accord with current building standards or are otherwise defective, any costs of repair, replacement or upgrading these items will be payable by you.

Where we mention or quote for any amendment, improvement or installation which uses the gas, electricity or water services in the property, this is given on the assumption that all services accord with current building standards.

Where our works take place around pipes and cables, this can obstruct treatments and, consequently, we cannot cover such works with any guarantee that we may issue.  This does not apply to electric cables which we embed beneath our plasterwork.

3. Timescales

Where we make any mention of the time that your project might take to complete, this should be considered a helpful guess, rather than a promise or guarantee. We encourage all of our clients to leave plenty of time between our work and any subsequent deliveries, services or installations which they might have planned to avoid clashes and the inconvenience of having to rearrange them.

4. Quotation

Our quotations are:

  1. Valid for three months from the date of its issue;
  2. Based on the assumption that the thickness of wall plasters requiring removal does not exceed 20mm, which is the standard depth in most homes.
  3. Based on the assumption that a 110v/240v power supply and clean water supply will be available to us on site throughout our works;
  4. Prepared for the benefit of you to understand the minimum cost that you will be liable to pay on the completion of the project. Where less work than that referred to in the quotation is required, a reduction of the figure in the quotation will be made.

5. Construction Design and Management Regulations 2015

The Construction Design and Management (CDM) Regulations 2015 require that our Technicians have ready access to a toilet and washing facilities whilst at work. As a result, you must ensure that they have access to a toilet and sink whilst on site. Our technicians are responsible, trustworthy and will treat your facilities with the utmost respect during their time on site.

If facilities aren’t available in the property, or if you would prefer our Technicians not to use them, we can arrange for a temporary outdoor facility to be installed nearby at an additional cost to you.  If this is your preference, please let us know in good time so that we can make the arrangements for you.

6. Party Wall etc Act 1996 and damage to adjacent properties

Where any of our works are to walls which fall within the definition of a ‘party wall’ (a wall which you share with a neighbour) as under Party Wall etc. Act 1996, you are required to obtain the consent of your neighbours prior to the start of any works. If you would like further information about how to do this, please consult the Government’s advice on this via the following link:

As part of our works, we commonly use heavy machinery to remove wall plaster from the walls.  These tools cause vibration, which can lead to hairline cracks, small holes and/or damage on the reverse sides of each wall; notably on the side of a neighbouring wall. Unfortunately, such damage is an unavoidable (but thankfully, rare) occurrence of using any drills or machinery on walls and, as such, any liability for repairing damage to the neighbouring property will rest with you. Of course, we are happy to assist with repairs where we can and we understand that such incidences can cause tension between neighbours, but we reserve the right to levy a reasonable charge, should additional work be required to carry out those repairs.

7. Listed buildings

If your property is a listed building (you should have been made aware whether your property was listed when you bought it), you should obtain the necessary permissions before any of our works are carried out. If no notice in writing is provided to the contrary, we will assume that all necessary steps have been taken by you to comply with the law.

8.Local Authority requirements

Where planning permission or any other permission is required before any of our works commence, you should obtain this long before your start date. If you are uncertain about whether planning permission is required, you should consult a representative of your Local Authority or qualified solicitor.

The planning application process can take quite some time, so it is sensible to allow for this, prior to setting a date for works to commence.

9. Asbestos and other harmful materials

Where we suspect that a building material containing asbestos or other harmful material is present in the property, we have a legal responsibility to safeguard your health and the health of our Technicians. In order to fulfil our duty, we must satisfy ourselves without question that there is no risk. To do this, we will arrange for a separate contractor to test and, if necessary, remove the material before work continues. We will inform you of what the cost of this will be, before proceeding.

10. Dust, dirt and disturbance

An inevitable and unavoidable part of any of our work is the creation of a considerable amount of dust and dirt.  This is particularly the case where wall plaster is removed and/or applied, and where the drilling of internal walls takes place.  Though our Technicians will endeavour to carry out their work in as reasonably clean a manner as possible, it is inevitable that dirt and dust will still be present after the completion of the works.  Where such works are carried out, it should be noted that dirt and dust can continue to settle for several days following the works, necessitating repeat cleaning throughout that time.

11. Redecoration

New wall plaster should be allowed to dry out before any permanent redecoration takes place. We recommend that a minimum drying time of 6-8 months is allowed in total. However, one coat of matt emulsion can be applied to each plastered wall as soon as it appears visibly dry; this normally takes 2-3 weeks.

If redecoration takes place too soon, this can result in peeling paint or wallpaper, or the appearance of a salt-like substance on the wall, to name a few consequences.

12. Payment and additional charges

Invoices will normally be submitted to you upon completion of the work and are payable within 14 days of the date of issue. Where we deem it suitable, we will issue interim invoices, which are similarly within 14 days.

13. Cancellation and postponement

Unforeseen events can always impact a project. We recognise that no one means to intentionally inconvenience one another, but we must ask, if postponement or cancellation of your project seems likely, that you inform us as soon as possible. Cancellations and postponements cause considerable loss to small businesses like us and, though we do not to seek to charge clients for the full extent of our loss, we do require some payment. Please be aware that you need to provide 14 or more full days’ notice to us to avoid any charges.

The charge for cancelling or postponing your project less than 7 full days from its start date is 5% of the total contract cost or £250.00, whichever is higher.

Clients booking a start date with us less than 7 full days in advance are still subject to the same rules and charges as those booking more than 7 full days ahead.

14. Delay and interruption

We recognise that no one intends to intentionally cause delay or disruption to one another. However, where we must, we will recover from you what reasonable costs or losses are incurred as a result of delays or interruptions which are caused by you or separate contractors which you have instructed.

15. Late or non-payment

As a small business, it is difficult in the current economic climate to extend our payment terms past our standard 14-day period. Much depends on the payments made by our clients, such as the wages of our staff and the payment of our suppliers. We will endeavour to remind you about the due date for your payment at sufficient intervals and would appreciate you making every effort to issue payment as soon as possible.

In the unfortunate event that late or non-payment occurs, we may involve our debt collection partners, ICMUK. You can find out more information about ICM at:

Where a case is handled by ICM, they will add an agency fee of 10% of the total contract value to the invoice.

We reserve the right to recover our reasonable administrative costs caused by late or non-payment. Further, interest will accrue, calculated daily at a rate of 8% Per Annum plus VAT above the Bank of England’s base rate for every full day following the expiry of the payment period that the invoice is not settled in full.

16. Finance

Where finance is offered to you, this will be on the basis that we are acting as an introducer for the purposes of the finance agreement.  Any terms and conditions of the finance agreement will be those stipulated by our partner(s) at the given time.  Presently, our finance partners are:

Omni Capital Retail Finance Limited

Oak House

Reeds Crescent

WD24 4QP

FCA Registration No: 720279 

Duologi, trading as Specialist Lending Ltd

10 Bressenden Place



Applications for finance should always be submitted and a decision received long before work is carried out.  Rejection of an application for finance does not exclude clients from any conditions set out in this document, including those relating to cancellation, postponement, delay or interruption. In addition, rejection of an application, does not exempt customers from paying for any works which have already been carried out on their project.

Allerton is not responsible for the decision of any of our finance partners.  Should an application for finance be rejected, Allerton will not be obliged to offer any form of credit in its place.

Allerton Damp Proofing Ltd is regulated by the Financial Conduct Authority (FCA), Registration No: 791947.

17. Guarantee

Where we have offered a Guarantee in our Survey Report, this is our Standard 20-year written Guarantee.  Since 1983 we have issued guarantees with much of our work, but we are proud to report that more than 99% of our customers have never needed to use them.  For further peace of mind, in addition to our Standard Guarantee we can offer Guaranteed Protection Insurance (“GPI”), at a further cost.  Under GPI, the Property Care Association will instruct one of its members to uphold the Guarantee if, during the first 10 years of our Guarantee, we cannot fulfil our obligations under it for any reason.  For further information about GPI, please contact us.

Please note that our guarantees:

  1. Only relate to damp proofing and timber preservation works, but not necessarily all works falling under that category.
  2. Will only be issued following the account to which they relate being settled in full.
  3. Are transferable on the sale or transfer of a property, for a fee of £50.00 plus VAT

In the extremely unlikely event that you need to make a claim under your Guarantee, please contact our Customer Services Team on 0330 111 3377 who will guide you through the process.

18. Additional work

In the event that, during our works, we discover that additional work is necessary, we will endeavour to consult you about the additional time and cost implications before proceeding. A non-exhaustive series of examples of the circumstances in which this can arise is set out below:

  1. If we are removing wall plasters as part of our works, we will need to ensure that the surface beneath the plaster is suitable to accommodate our damp proofing systems.  If it is the case that the surface beneath the old plaster is coated with gloss paint or similar coating, this may need to be removed before new plaster is applied.  We can arrange to do this for an additional cost;
  2. Where moisture has entered into a building due to rising or penetrating damp, it is possible that fungal decay, which would weaken structural timbers, may be present and hidden behind wall plaster and skirting boards.
  3. Solid floor removals can sometimes be hindered if they are reinforced with steel, our quotation to remove a solid floor is always based upon the assumption that no steel is submerged in the floor. If this is discovered once work commences we will have to adjust our quotation to accommodate for the extra effort and time required to remove this.

Where the thickness of any wall plaster which we have quoted to remove exceeds a depth of 20mm, an additional charge for the additional labour time taken to remove the plaster will be necessary.

19. Furniture and fixtures

As part of our works and quotation, we may have included a charge to remove and/or reattach fixtures and fittings as part of the works, such as:

  1. Radiators or other heating units;
  2. Pipework for water or gas;
  3. Fixed items of furniture; and
  4. Kitchen units or appliances.

Where we remove and/or reinstate these items, some reasonable wear and tear may occur during that process. For instance, kitchen units are not designed to be removed, once they have been installed. So, depending on how the units were fitted, it may not be possible to remove them without breaking parts; this is especially the case where such units have become damp.

20. Snagging

In the unlikely event that we have to return to a job to carry out additional work, following completion of the project and the issuing of your invoice, the following will apply:

  1. Even in the event that snagging is required, 90% of the total invoice is still due by the due date (if an invoice has been issued). If a 90% payment is not received by the invoice due date, our late payment terms will apply.
  2. Following completion of the snagging list, the remainder of the invoice is due in full within 3 days of our departure from site.  If payment is not received within this time, the late payment conditions in this document will apply.

21. Changes to our designs

In the event that, during our works, our technicians determine that a different system than the one originally proposed will benefit the property and provide a more effective solution to the identified defects, this will be changed with the approval of your surveyor. Any such changes will not necessarily be subject to a reduction or increase in the price of our works. Any increase in price will be reported to you and your approval sought before the works are carried out. Of course, any changes to the system which will result in a noticeable difference to the internal decoration of the property will be raised with you in advance to ensure that you are content with the new design.

22.Customers outside of the United Kingdom

In the case of customers whose main residence is outside of the UK, we may require payment before the start of any works.

23. Resolutions

Where we cannot resolve customer complaints using our own resolutions procedure, our non-commercial customers are entitled to use the Dispute Resolution Ombudsman service. If you wish to refer your complaint to the Ombudsman, you can contact them on 0333 241 3209.
