(The work turned out to be considerably larger than originally thought). Everything about this company was excellent. There were no extra charged. I would recommend these people based on our experience with them.

Truly fantastic customer service. Removed all existing windows and door, replacing them with brand new materials. The team did not stop from the moment they arrived until the completion. Extremely polite and nothing was too much trouble. Excellent value for money, could not recommend them highly enough.

Placed advert Thursday. Contacted same day by Mike with a view to coming out and quoting next day. Came on time priced the job on Friday and arranged to start work on the Tuesday. Mike worked with his son Silas. What a really nice pair. Genuine, polite and got on with the job even though I asked for a few tweaks along the way. Both very old school and worked at their own pace - happy with work carried out and will use them again. Reasonable price too.
