Extensions- 1 Jan 2020
The Fulchers completed a single story extension for us and we are really pleased we chose them. They have been brilliant from start to finish- competent, reliable and professional. Build was completed to original quote and they were happy to add in some additions as we went along and charge accordingly. Will not hesitate in recommending them and we actually miss having them around!

Exceptional commitment to pleasing demanding customers. Unusual attention to regular communication by txt Whatsapp and email throughout the process with thoughtful contributions to the evolving design and endless patience as we changed our minds. Excellent attention to detail and delightful approach to the whole process. First class team of other trades (electrician, painter, plumber) whom he project managed good humouredly and effectively. Remained on site throughout despite additional work to original specification and competing demands on his time. Extremely high standards of plastering, joinery and overall finish. Trustworthy and made the whole experience of house renovation a pleasure. No hesitation in recommending James. Will definitely keep him on speed dial for when we have more work!

Extensions- 11 Aug 2026
I hired Spindrift Services to complete my extension interior. This included tasks such as: - Batten plasterboarding throughout - Insulating the floor and laying the boards - Cutting through my external wall into my kitchen - Installing a new bathroom - Building a new timber frame entrance - Installing frames and doors Here are three reasons why you should hire Liam and Michael for your project: 1. Their estimate was accurate, and I appreciated that payments are made in logical stages. 2. At multiple points in the project, they guided me through details which I hadn’t considered before they became a blocker or issue, giving my wife and I time to think them through. 3. They are punctual, hard-working tradesmen, and the quality of their workmanship is top-notch. I’ve enjoyed every part of the experience of working with Liam and Michael, so much so that they will be replacing my kitchen next.
