I have just had a porch built by JC Windows. I hadn't used this company before but they came highly recommended and I can see why. Everything went smoothly from start to finish. Everybody I dealt with was friendly and efficient. Best of all I love my new porch. Will most definitely be using this company again for further jobs.

Company very easy to deal with. Easy to contact and quick to respond. Had double glazing replaced in lounge windows set in hardwood frame. The survey beforehand was very helpful and the work was carried out with no inconvenience to us, no mess at all during or after completion. Would definitely recommend this company.

From start everything was meticulously planned and team who fitted our triple glazing were highly skilled, hard working, trustworthy and very professional. This is our second big project and was completed to a high standard and the quality of the windows were like all the products supplied by this JC of an exceptional standard. The final thing was the cleanliness of the team which was exemplary and they even rehung our curtains. A very positive experience.

Two workmen arrived on time and had the job finished to our satisfaction, tidying up after themselves in just three hours. Lovely new Windows and no traffic noise at long last. Thank you very much.

Really easy to deal with, friendly and professional folks. Did a superb job of my bay windows plus guttering, facia boards and sofits. Competitive and accurate quote provided and they kept me up to date all the way. Highly recommend these guys and would happily use again if I needed.

We hate traffic noise so why did we move into a grade 2 barn conversion with hardwood windows right on the roadside of a country lane? Why indeed, because we loved the property. After 2 years of putting up with noisy tractors and boy racers at certain times of the day and night we decided to invest in secondary glazing. We like to deal with companies from our area of Lancashire if we can and googled ‘secondary double glazing’ near me. Up popped JC Windows. We contacted them and told them what we wanted. John gave us a quote and we arranged for him to measure up. The windows were ordered and ready for fitting sooner than advised. The fitter arrived, explained what he was going to do and got on with it. No fuss and no mess for us to clear up as he did it all. We are so pleased with the result. It has made a huge difference and you do not even notice that they are there. We would definitely recommend J C Windows for secondary glazing. So pleased we found them.

Really think the title tells it all. Had a patio door and new window in lounge installed, which involved the removal of brickwork with both windows. The guys were friendly and competent and I would thoroughly recommend this company.
