Testimonials


“I recently had the pleasure of working with GP Contracts to silicone my kitchen & two bathrooms. The work was completed to the highest standard. The team was punctual, efficient, and meticulous in their attention to detail. They also took great care to protect all of my fixtures and fittings. I am absolutely delighted with the finished result. I would highly recommend GP Contracts to anyone who is looking for a reliable and professional mastic sealing company.”

★★★★★

- B. McCormack, Glasgow

“I have now used GP Contracts on a number of contracts to carry out mastic pointing and have found the company very easy to deal with from the Directors to the operatives on site. The company and its employees have never let me down and all work carried out for us has been to a very high standard. I have recommended GP Contracts to my collegues and they have now established themselves as our main sub-contractor for mastic pointing.”

★★★★★

- G. Neil, Contracts Manager, Laidlaw Scott

“I was very pleased with the work GP Contracts undertook at my house. The mastic around my windows had become detached allowing water to seep through. GP Contracts meticulously removed the old sealant and replaced it with new high-quality sealant, which not only enhanced the aesthetics but also effectively resolved the water issue. I am now completely confident in the integrity of the mastic sealant. Thank you!”
