First time using Cosyhomes Windows and it won’t be the last. Great service replacing 2 glass unit for a loft room and fixing a broken lock. Great local company with lovely pleasant people.
From start to finish Rachel in the office and the lads on site were brilliant!! Nothing was a problem!! Neat tidy work and excellent finish!! Definitely recommend these guys!!
I have been working with these guys for years. We recently had new windows fitted by this fantastic family-run company, and I can’t recommend them highly enough. From the moment we received the quote from Rachel to the final touches of the installation, the entire process was seamless and stress-free.
