Lee Vine construction did a wonderful job on our renovation and extension, keeping in contact about all aspects and finishing to a very high standard. We would definitely recommend them!

We are delighted with the work that was carried out on our home . The quality of the work the ideas the guys brought to the work and the total professional attitude they had to their work . The guys were respectful to our home and have a friendly way about them. We would highly recommend these guys to anyone who wants good quality work done on their home. Kevin and Lindsey McCloskey

Really pleased with the work Lee Vine Construction recently completed for garage conversion into a utility and playroom. Matt and his team maintained a high level of professional throughout from start to finish. Extremely detailed quote meaning no hidden extras, turned around really quickly and to an excellent standard, Matt went above and beyond to find exact matches of what we were looking for (Windows, brickwork, internal door etc). Very happy and would definitely recommend.
