Fantastic job
Customer Service
Having work done in your home can be a headache for many reasons, but Jason & his team made it so easy. I was kept informed all along the way. The guys working on the job were meticulous in their work and ensuring my home was left as clean as possible each night. Plus I felt comfortable leaving my house keys with them just to get on with it - and they did!

Brilliant job
Customer Service
Even though Paul was working 24/7, he & his boss made sure that he could do the job of fitting both a new window and a door in the time we needed, so he came & worked all day Sunday!

Excellent Product & Service
Customer Service
Not the cheapest quotation we had - by some margin - but the design of the windows was what we wanted and we hoped that by paying more we would get more. We were not disappointed. Installation was efficient and relatively dust-free.

Good Work done Quickly and Efficiently
Customer Service
We are very pleased with the work that Alpha Home Improvements has done with our windows and patio door. They arrived on time and got the job done well and quickly. Mess was kept to a minimum and cleaned up afterwards. Would definitely recommend.
