Company info

Hi we are Cromwell Damp Proofing and Plastering Services, a friendly family run business.

We aim to give a 100% professional friendly service and leave with a flawless finish.

We take pride in our work and are always reasonably priced giving full breakdown quotes for total piece of mind.

Unlike most damp proof installers who are only certified to install a chemical damp proof course with a partial guarantee and just want to cover your walls in a plastic membrane to mask the problem, we dig deep to rectify the underlying problem first.

One to note is most of the so called 'damp proofing companies' out there are not college or NVQ trained in any way and have simply attended a 1 day course which teaches them how to install a DPC cream only.

Any member of the public can do this. 

We are certified damp proof installers and qualified plasterers so with us you receive a 'full guarantee' that both the damp proof course and replastering has been done to the very highest hard to beat standards.

We plaster the walls after we have installed the damp proof course, giving total piece of mind that we are giving a full guarantee for the damp proof course (DPC) and a full guarantee for the plastering too.

Our edge above other company's is rather than having three lots of tradesmen entering your home 1, damp proof course installer 2, plasterer 3, joiner to refit skirting we do the job from start to finish. Usually by the end of the job in hand you will know us quite well.

All our damp-proofing comes with a 10 year government recognized guarantee.

This is all you need to buy or sell a property when that dreaded survey highlights 'damp issues'.

Honesty is our trait, and if the works your asking for honestly cant be done, we wont do a quick fix and run under a pretense we've solved the problem only for it to come back some time later. We will advise you on what to do and simply help by pointing you in the direction of the adequate professional you need.

I first started damp proofing and plastering at 15.
I attended Stockport college full time to complete a 2 year diploma giving me level 1 and 2 in hand plastering and construction knowledge.

I then worked for New charter housing trust primarily working along side surveyors diagnosing all sorts of damp, condensation and penetrating damp issues in void properties. Once the correct causes of damp were found I would get to work removing the plaster installing the damp proof course then re plastering the walls to a perfect finish. I also became an approved contractor to install damp proof course and give full guarantees for both damp proof course and plastering, it was by this point I went one step further and completed my level 3 NVQ in hand plastering and construction knowledge.

After new charter I left on good terms (still regularly do damp proofing for them) to become independent. Since then I have built up a large portfolio of builders and property developers who trust us to fix and treat all aspects of damp in their vacant properties. We also source and find our own jobs and have many returning customers.

Thanks for reading.

Damp proofing and replaster of my living room wall after a leak from next door

Verified Review

Aaron was great - good communication, expert work completed and very conscientious in terms of cleaning and the finish on the job. Would absolutely hire again.

Removed old plaster, filled void with rock wool, covered with thermal backed plasterboards and skimmed

Verified Review

Highly recommend! Had damp patches on all three bedroom and landing ceilings - Aaron took a look and knew straight away what the problem was, explained it all, quoted the same day, stuck to the time he said it'd be done in (four days) and stuck to the quote, plus doing extra job of taking out the top of a fitted wardrobe - at no extra charge. He sent regular updates and videos, clearly explaining everything he was doing and why, and did a great clear up job considering all the ceiling eaves were essentially ripped out! Really friendly too - all round excellent service. Thanks!

Renew gable end DPC and return wall to kitchen including the nip around kitchen door

Verified Review

The bottom line is all the the work completed to agreed schedule and to a high standard. I found Aaron to be reliable and he went the extra mile to make sure he kept me in the loop over the days he completed the job. Pre job he provided a detailed written quote along with details of the guarantee and completed work plan he would supply upon completion. Its a really dirty job but my house was left clean and tidy afterwards. I have the skirting boards back on and the walls have been re painted. I'm really pleased with the end result, looks great. I would be happy to recommend Cromwell.

My Porch inside wall felt damp. I needed some expert help with the issue

Verified Review

I called Aaron and explained the problem. He sent his dad over to have look and it was decided rather than taking the wall down back to the brickwork ( saving me some money, it is a small wall) was to use a spray solution to resolve the issue. These guys know what they are doing what ever the problem . Aarons dad even fixed a floor lamp for me . So happy!
