very pleased customer

5
We are very happy with all the carpentry work DMI did in our house. I have since recommended them to a few of my friends. DMI were able to think creatively about the job and came up with good suggestions on how we could improve the end result. Their service was friendly and accommodating, they took great pride in finishing our job to the highest standard. Thank you.

New sash panels with draught proofing

5
We ordered 3 sets of new sashes to replace our old and rotten panels. Dave made and delivered the sashes within a week and installed in one day. The draught proofing is making a big difference as we were struggling before to keep the heat especially when cold and windy.
The price was very reasonable and in comparison to other sash specialists probably the best value for money.

Saved our Victorian Window

5
Our Victorian coloured glass bathroom sash window had developed severe rot at the bottom, requiring specialist repair. DMI quoted quickly for removal of the window, offsite repair with new wood and resin, and reinstallation. The work was completed very professionally in two days, with no mess or disruption. Very happy with the high quality result, and would use again, and recommend.

A fantastic experience- will use again!

5
An excellent and friendly service from start to finish. The quality of work is outstanding so we hired the company again for more work and also recommended to others. We recently had an issue with one of the windows which was addressed and fixed on the same day! We were able to have double glazed sash windows in our existing boxes which many companies said would not be possible however DMI saved us thousands ££. Will definitely use again.
