Dry rot was found in one of our rooms, following a leak. The window lintel needed replacing and the whole area treated.

"From the first phone call through to the end treatment, the team were fantastic in dealing with the dry rot problem in my home. They are professional and importantly a calming presence in what was a stressful time. Workmanship is excellent and left my home clean and tidy, pricing is good too. I highly recommend and definitely use the team again if needs be."

Repointing front elevation of house, drainage work at rear of house, removal of interior boarding in one room, timber and brick treatments, replacement boarding and plaster.

"We had a really positive experience from the initial survey to completion of the work. We felt really looked after, everyone we worked with was professional and thoughtful. It was quite a lot of work over 10 days, and each day the team made it as easy as it possibly could be. The quality of the work was really impressive, and communication was above and beyond all expectations. Thank you!"

Treatment of Dry Rot in bedroom.

"I absolutely cannot praise this company enough. The same day I rang for help, an inspection was arranged for that afternoon. I received a written quote next morning and when I rang to accept it, the work started the following day. I was kept up to date every step of the way and any queries (email or text) were answered within hours.

The work was quicky and professionally done. The workmen cleaned up after they finished each day and caused the minimum of disruption they could. I am very happy and grateful with the results.

Damp proofing, re-plastering, wall removed and new ceilings.

"From start to finish we found Haydn and the company very professional. We were kept informed every step of the way and informed of any changes.
We had an issue on completion and it was addressed immediately.
We also changed original work twice and this was never an issue and an amended invoice was provided very quickly.
Highly recommend A***

Damp on living room wall. The company investigated and then hadnto open up an old chimney breatntonascertain the cause, treat and then rebrick up and make good.

"Rhondda Damp Proofing recently investigated n issue with damp on a living room wall. From the surveyor who came to the colleagues who then opened up the chimney breast, removed all the damp rubble and soot causing the issue and cemented qnd replastered, all were thorough and professional.

I dreaded the thought of having this done but they worked quickly and thoroughly, cleaning up each time.

I would have no hesitation in using them again."

Kitchen wall tanked, the two men that removed the old plaster and cement were very efficient , very friendly , and I was totally amazed at the skill in the re rendering and plastering they carried out, although it was a very very dirty dusty job , an old black Mortar wall they cleaned up after themselves , the electrician was very efficient as was the plumber they made a cracking job of refitting my utilities, would I recommend them , Yes, would I use them again , Yes. My Wife and I are more than pleased with how they worked a credit to your Company, cheers Len

"Other than not having a working kitchen for a few days the whole experience was not as bad as I feared. The workman as far as they could cleaned up after themselves however they could not control the amount of dust raised so the adjoining rooms got very dusty, I did not think about this or would have sealed off as much as I could. I would recommend to anyone having this sort of work done to seal off any rooms not in use. Overall it was a pleasant experience having this work done by this company and I cannot praise them enough, cheers Len"
