Fast, Clean and Reliable Job.

I recently moved into a new home where the sealant in three bathrooms and kitchen were in desperate need of a tidy up. I called CLARKESEAL and James agreed to come in and do the work for me.
I was amazed by the difference it made to the place having the sealant re-done.
I would recommend to anyone looking to tidy up their home.

After 4 years in a new build flat the bathroom and kitchen sealant needed re-doing in some areas. I contacted James and he did the work a few days later. He has got years of experience and is very professional in his work. It was very satisfying to have a brilliant job done.

Just used Clarkeseal for a major renovation on 34 flats and must say was very impressed with both the quality of the work & the time in which it took to be completed. I've used many mastic companies over the years but the service given by James was excellent and at a fair price. Will be using this company again in the future and I urge others to do the same!! You won't be disappointed!!..

After having my windows replaced in my house I was left looking for a mastic company to complete the sealing work as the fitting company said it was a tricky job.

I called CLARKEseal and they were extremely efficient, coming to the house and providing me with a very reasonable estimate for completing the work.

The job was finished in less than a day and the quality of the work was really excellent!

Overall, fantastic service and superb quality work - very satisfied.
