From start to finish the company were very professional. Everything was explained to us. Despite the work being very messy, everything was cleaned up at the end of each day. The two lads who completed the work, Wes and George, were hard working, polite and answered my many questions without any problem. The work was done to a very high standard, and it exceeded my expectations. I would highly recommend RTC, I would not hesitate to use them again.

Transparent Pricing & Top-Notch Workmanship

From initial contact with the office, to the visit from the surveyor, the surveyors report which was very thorough as he actually went under the floors, the price for the work and the quality of the job itself was excellent. The surveyor Sam did an excellent job as was the repairs done by Dan and Karl. After the work was completed, I was contacted by the office to check that I was satisfied with work and the quality of the job, which I was. Professional all the way through with good customer service, made to feel I was important to their business. It’s an old adage but big enough to cope and small enough to care fits the bill. Would use again and would have no reservation about recommending them.

Professional from Damp Report to Final Plaster

Delighted with the service. RTC installed a damp proof course and replastering at my house. The damp survey was professional, detailed and very clear on the work to be done with good accompanying explanations of the issues. The office is easy to contact, answering all my calls and returning them promptly if the person I needed to speak to wasn’t immediately available. The technicians who performed the work were professional and worked fast and hard. They explained clearly all the steps and left the house clean every day. I am really please with the final finish and overall result. They were not the cheapest quote or survey I had, but at all steps were the most professional. Highly recommended.

Protected Home, Perfect Finish—Excellent Result

Originally recommended by my surveyor after discovering damp in 5 rooms. All the RTC staff were friendly and did a great job in minimising the dust and mess with protected sheeting and flooring throughout the house. The final result is excellent and a big call out to Steve for helping with moving a very heavy radiator and giving me tips on cauking. Highly recommend if you want a fairly priced job by hghly skilled employees and not subcontractors.
