We were very impressed with Dan’s attention to detail, standard of workmanship and care taken. We were happy with the original installation but it is a tribute to Dan that he identified an issue and came back to do more work until he was satisfied it was just right. Dan kept us informed of progress and was very pleasant to deal with. When we had an issue with planning permission Dan provided detailed drawings of the sash window specifications. No hesitation in recommending. Windows look lovely.

Had a quote for roof repair which included for 1 missing tile, re fitting existing tiles, repairing flashing and gutter cleaning did not accept quote. On advice from another roofer just had the one missing tile replaced since there was no evidence of any leaks inside the loft or 2nd floor ceilings.

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.
