Simon Anslow

Five star company, had a door installed and I was very impressed with the service. The installers were clean and tidy and they removed the old door from my property. I would highly recommend. Will be getting more work done in the next couple of months.

Jayne Burrows

We have just had our old fascia boards, guttering and downpipes replaced and are extremely happy with the work completed. The two guys who did the work were very professional and experienced and clearly take a pride in the work that they do. They both worked extremely hard during some heavy downpours and we would wholeheartedly recommend JWS Home Improvements to anyone who may be interested in getting similar works completed.
