Fitting French doors and a new back door
Very professional first appointment with James. A reasonable price was agreed to replace our existing patio doors with French doors and change the back door for a new one. A short timescale from ordering to fitting was achieved and the fitters were exceptional. Very neat and tidy and did a lovely job. Thank you.Verified reviewerJob location: SA18RRobin J10 Double Glazing Installation

Good quality insulation
I had 6 windows fitted and what a fantastic job, the window fitters were exceptional, they told us everything that they were doing and kept us well informed. I will be calling them back to do my front door. I recommend this service.Verified reviewerJob location: CF310 UPVC Windows Installation

Highly recommended.
We have used A-one for the supply and install of 14 units across multiple properties in Swansea, in all cases the products are of good quality, great value for money and we have not had any issues. The whole process has been excellent, from initial visit from James, survey and installation. The installation team of Matthew and Morgan were super efficient, tidy and took a clear pride in their work and displayed a commitment to deliver a quality installation. As a property business owner I deal with a number of trades and am happy to recommend A-one for doors and windows without hesitatationVerified reviewerJob location: SA1
