Just to say thank again. I spoke to my builder and he confirmed that your specialist had attended and given the "all clear" and that your damp work was all now fine and we can finish off our refurbishment.

- Nick Mottershead

The estimate came promptly, the price seemed reasonable and the work was done with minimum disruption by very pleasant staff. It was a good experience all round.

- Stuart Nattrass

I would like to thank you for the work you carried out to our house in Chalfont St Giles. We had patches of salts appearing on the walls affected, and recommended a course of action.

You organised for your team to come and remove the plaster, inject the damp proofing treatment and re-plaster the affected area. Your team both at your office and the teams that came out to do the work were professional and friendly. I had to change the start date and your company had no problem accommodating my request.

I have no hesitation in recommending you to my family, friends and clients.

- Annemarie Shipman

We used Quadrant for damp proofing the ground floor of our home. We found them to work diligently in getting the job done. All questions and concerns were addressed by the team. I wish to express a special "thank you" to Ellie, Paul and Rob. I can also say that both Rob and Paul cleaned up after the job and Ellie always provided a polite, professional and proficient service. I recommend Quadrant to anyone looking for damp treatment. Thank youread more

Very helpful, a professional report was done, the guy who came to see my property was on time and polite. He sent me a very detailed report explaining that the problem was condensation not damp, and how we can prevent this in the future. I contacted many other companies, some wanted to charge me for a survey, some didn't turn up and one was rude to me down the phone. I can't stress enough how pleased i was with this company's attitude, I would recommend them to anyone.read more
