Specialists in replacing roofs, slates or tiles. I source and supply all materials saving the customer time and hassle researching the materials. All of the materials I use are of the highest standard. I always supply samples of tiles or slates to ensure we get what suits best for your property and price range. I also do new build houses from wall plate to finish and fit fascia boards and soffits. Other jobs we regularly complete include full loft Conversions and replacement of old roof windows due to them becoming drafty or if they have been fitted for 25 years and over and need a upgrade. All of my jobs are completed to a high standard and come with a 10 year warranty.

We chose Timber Box Sash Windows to double glaze our sash windows after Andrew came out and surveyed, then followed up with a really decent quote. We got the work done in two phases and both times were really hassle free with the joiners turning up on time and getting on with the job. They were a real pleasure whilst they were here. Very polite and friendly. It’s good to have the same person that surveyed the job actually carry out the work as well, makes for a really smooth process.
