What People Are Saying
“A complete saviour when giving advice and completing works to my first home. Amazing work with the service to match! I wouldn’t go anywhere else.”
— Jade
“We have used Ryan and his team for many years now. They are extremely reliable and do a fantastic job. They have completely gutted our bathroom to make it bigger and knocked our kitchen from 3 sections to one huge area and gutted/fitted it all out. The latest creation was an outdoor area with a pitched roof we used for entertainment and I also film classes in it. I would never go anywhere else they are brilliant!”
— Helen
“Couldn’t recommend J&S Grimmer Builders enough. Efficient, friendly and hard working team. All work completed was to an exceptional standard. So pleased with our new extension”
