” We had a very good experience by using Lancelot Windows, they were recommended to us, we visited their showroom where they answered all our questions, gave us plenty of advice etc, with no pressure selling comments, the owner, came to property to do a survey, which showed that we would benefit from new windows and external doors, (which we already suspected). They gave us a very good quote, which we agreed to.
The 3 man installation Team were very organised, explained clearly what they were going to do, they installed 5 windows and 2 external doors in just 2 days, gave us a demonstration and some tips about maintaining them.
We would definitely and confidently recommend this Company.”
Mr & Mrs Grant  Burnham on Sea. Somerset
” A huge thanks to Lee and the whole team from Lancelot. We have been very impressed with the quality of their workmanship, their communication and friendly but professional manner. We first contacted Lancelot on a recommendation from a family member and we are so glad that we did. After our patio doors and window were fitted we asked Lee and the team to come back to complete some more work on our house as we honestly couldn’t fault them. Thank you so much for taking such pride in your work, it’s really made a difference to our home.”
Mr Meech Weston Super Mare
” An outstanding effort made by the installers of our front door. Callum and Toby were professional, friendly and looked like they were enjoying their job. They were tidy, clean and neat, even in the sweltering heat. The door looks stunning. ” Well done Lancelot team!
Mr Akhurst  Street  Somerset
” Unlike another local company, Lancelot don’t go round knocking on doors, or use unsolicited phone calls to get business. They don’t need to, because they’re highly recommended by the people that use them. Also unlike the other company, they don’t pressure sell, and are very competitive with prices. Pleasant, friendly lads got the job done quickly, left the place clean and tidy. I’m very happy with the quality of the doors, too. “
Mr Craig, Glastonbury Somerset
” Lee and his team at Lancelot have done a marvellous job of replacing our conservatory, for a good price. They got the design spot on, for the location, use and look of our conservatory. Then their construction was delivered as planned and quoted. They did the whole job in under 3 consecutive days, actually finishing a day early, with great attention to detail, and fitting in well with existing structures like our guttering. They were punctual and kept us informed of what was going on, and very polite and pleasant to work with. Tidying up and cleaning up after themselves “
 Kind regards, Kathy at Porlock
A big thank you to Lee and the whole team at Lancelot for wonderful service from start to finish. Everyone was friendly and prompt. After fitting our lovely new front door they left the area clean and tidy and were thankful for refreshments given. The job was completed well ahead of schedule. Highly recommended.”
Mr & Mrs Fraser , Wells , Somerset
We just wanted to say a huge thank you to Lancelot Windows and Conservatories – right from the outset the service has been fantastic. Lee and Kelly were brilliant in helping us with making the choices for our home, making useful suggestions and were very patient whilst I ummed and ahhed about the front door!When it came to fitting Callum, Toby and Hayden were great. They were always very polite, punctual, hard working and completed the job to a high standard.

We were really impressed that the job was completed in a timely fashion within the timeline promised and it was great to support an independent local family business. Thank you for making such a difference to our home. “

Mr & Mrs Fisher . Wells , Somerset
” I had replacement fascias, soffits & rwg’s replaced at my mother’s bungalow.
Lancelot were competitively priced and I was pleased to be able to use a local Company for the work. Quote was detailed & Lee explained the work well on site & in quote, communication throughout was very good with Lee & Kelly in the office.
Guys on site worked very hard & carried on working through some appalling weather (neighbour said they were drenched), to a high standard. Very minor snag, just an oversight, was carried out within a couple of days which was good.
Overall, very satisfied with the Company and the work & would recommend. ” 
Mr & Mrs Clark, Glastonbury , Somerset

” I would like to say a big thank you to Lancelot windows, this ,family owned business we’re excellent in every way from the quotation to the installation of the windows and doors .

Lee the owner , who did our quotation was a true gentleman ,he listen to our requests and he gave us brilliant suggestions ,how we could improve the look of the property and for example having privacy glass in the bathroom top window and also installing an additional beam across the middle of the windows , these suggestions made the look of the cottage even better.
Callum (son ) and the two other chaps was so professional while doing the install,nothing was too much trouble ,they explained exactly what was going to take place , gave us different options for Silicone on window edges,colours from brown or white ,also the sizes of stripes that would go between the window and the wall, they cleaned up after every window install.

Customer service were exceptional in every way and I would highly recommend Lancelot windows to anyone looking to have there windows and doors replaced ,and I would definitely use this business again .

Don’t use a National company use this local family business.”
