HULL'S LOCAL DRY ROT SPECIALISTS

Curing Dry Rot for over 36 Years
DRY ROT
Dry Rot is the term applied to timber decaying due to certain fungi; once identified, this problem needs addressing quickly as the rot can travel behind masonry and all timbers and cause significant and eventually costly repairs to be required.
The problem can be quickly contained, and the rot eradicated if dealt with quickly.
Once the problem has been dealt with, we can replace any damaged plaster or timber, leaving you rot-free, along with a 20 or 30-year guarantee after a thoroughly professional job by Damp-Tech treating Dry Rot for the past 33 years. Call now for a free survey and quote

Customer Review
Dan did some work for me last week and I have to say what a top bloke, from start to finish he was a total professional and the standard of work was excellent and not to mention very tidy.
I wouldn't hesitate to use Damp Tech again.

Customer Review
Dan and Lee carried out damp proof work on our property, both inside and out. They were extremely courteous and respectful when working in the house.
The mess was kept to an absolute minimum and they cleared up as they went along. The finish on the inside plastering is perfect.
We would have no hesitation in recommending them to others and using them again if needed in the future.

Customer Review
Damptech sorted our internal rising damp. Did a great job, very professional explained everything cleared up all the mess too. Would recommend them to anyone. I would use them again.

Customer Review
Recently had some treatment for damp. Dan was very professional and friendly, explaining the treatment that he was undertaking for this.
The work carried out was to a high standard, also cleaned up the area once finished. Would highly recommend their service. Definitely would use again if needed. A very happy customer.

Customer Review
Other than the walls needing wallpapered, you wouldn't know the guys had visited the property. Both down to earth and polite considerate. Dust sheets placed over furniture and carpets protected.
The house was aired well whilst initial drilling being done. Left property very clean and tidy would certainly recommend. 5 Stars are given to both Dans.

Customer Review
We would be happy to recommend Damp- Tech.
I contacted them on the basis of good feedback visible on the company's website, and Dan Senior made a preliminary visit to inspect the problem, explain what was wrong and talk us through what the remedial work would entail.
The quote was fair, and the timing of the job was arranged to fit around our work patterns Throughout the process, the two Dans kept us updated on the stages of the work, were scrupulously respectful and tidy, and did exactly what they had promised, on time and on budget.
Many thanks.

Customer Review
Hi, Dan thanks for a quick, clean and efficient job would recommend damp-tech to my family and friends.

Customer Review
Hi dan thanks for a quick, clean and efficient Job.
I would recommend Damp-tech to my family and friends.

Customer Review
Recently damp tech came to our school as we had some problems with damp in one of the rooms, they first made an initial visit to explain to us what was the problem and how they would resolve the issue.
When they came back to repair the damp they were very thorough and respectful, the finished plasterwork was very good and they kept the area they were working in very clean and tidy. I would most certainly recommend this company.

Customer Review
We would highly recommend Damp-Tech.
We recently purchased a house and the survey highlighted some issues with rising …More

Customer Review
Me & my partner came across Damp-Tech when looking for a contractor to come and replace some rotten joists/ flooring, treat some woodworm and inject a new DPC. We met Dan for an initial survey and agreed a very reasonable price for all of the above to be carried out, all of which was done within a week.
Dan did a really professional job and was a pleasure to work with. We are keeping him in mind for any further work we might require, and would recommend him to anyone who thinks he might be able to help

Customer Review
Delighted that Dan could sort out the damp problem which had perplexed another tradesman. He identified it as soon as he saw it, within a couple of hours I had received his quote and arranged for him to do the work, luckily he had time to slot this in before he started another much larger job.
He came very promptly, over the course of two half days he did the work required. He left my home spotless, the only way anyone would know he had been was by the plasterwork that has been done, if I had been able to paint it yet, it would be invisible. I would highly recommend Damp Tech and if I ever have another issue with damp he will be my first call.
