Allerton Windows built our new extension and it’s absolutely lovely! The whole team have been brilliant from start to finish. The level of care and attention to detail during the process was second to none. Everything we wanted no matter how unusual, we got. Nothing was too much trouble. We can both be indecisive but the team had the patience of saints!
They continually checked in with us during the building process to make sure we were happy. I can honestly say our extension far far exceeded my expectations. Many thanks for all your hard work.

We have recently had our extension completed by the team at Allerton Windows and we are extremely pleased with the end result. The person I dealt with has been great throughout the whole process - checking on progress and helping us throughout with and questions or queries. All of the workmen involved in completing the extension were professional and friendly and all work was completed to a high standard. We would happily recommend Allerton Windows to anyone based on the service and quality of work we have received.

After having several companies quote for our extension we went with Allerton due to the amount of positive reviews and the person's knowledge and honesty. All the options were explained and there were no hidden costs. We were provided with a start date and they arrived the day before to check there were no access issues. They began work on 05/11/19 and finished on 04/12/19, every day we were informed what would be happening the day after. We were so impressed, all the workers were helpful and answered any questions. I can’t fault them and would highly recommend them. Thank you.

Allerton windows recently replaced our windows at the back of the house as well as installing french doors and replacing a flat roof to a pitched roof on a small kitchen extension. Extremely professional is the only description I can give. The work carried out is first-rate and the workmen were a pleasure to have in the house. such excellent workers. I picked Allerton windows based on their reviews and I can see why they're so highly thought of.
