Customer Service
We discovered a problem with rising damp when having some decorating done. Found Trustguard on Which? Website and contacted them based on reviews. Don came out quickly to assess the job and was able to give me a price at the time. Price was agreed and date given to commence work. Came when they said they would and did a fantastic job, very friendly and professional.Cleaned up afterwards too! Stacey in the office was lovely and so helpful. Would highly recommend this company.

Very good service!
Customer Service
Trustguard Ltd. carried out some damp proofing in my home. The work was completed in the agreed timeframe and at the agreed price. The gentlemen who worked in my home were friendly, approachable and kept me informed of the work as it progressed. They also maintained the space and tidied up regularly while they were working, which was very much appreciated. I also received good telephone communication before and after the job was done to check that I was happy with everything. I would definitely recommend Trustguard Ltd.

Don arrived on time of agreed date, carried out the work and as per estimate cleaned up and even put our carpet back. Stacey was also very helpful and organized a paper copy and email copy as requested. Would definitely recommend.

Damp proofing work
Customer Service
I contacted Trustguard regarding a problem damp area in the second bedroom of our 1930s bungalow. Don visited in person to survey the area and then I received an email confirming the quotation, together with copies of their insurance details and certification documents. To have everything in writing was very reassuring, and one of the reasons I went ahead with their quote. The guys arrived promptly as arranged, and the work was carried out quickly and efficiently, with minimum disruption. The area was tidied and cleaned afterwards and I’m very pleased with the result! Thank you! Since making payment I’ve received a receipt and guarantee. Trustguard is a reliable, efficient and trustworthy company. I’d recommend them to anyone.

Had rising damp issue in living room and hallway.had a quote in the winter and was happy with it but waited until the summer to get work done. Was a big job took a week as they said it would, very happy with work completed. They even did more than expected, doing extra plastering work to match and even out all the walls. Very friendly team. Cleaned up afterwards and left place very tidy. Would recommend to anyone.
