Had them out to fit 2 doors, it the 3rd time used them. They done great job has always, only thing that let them down was no number on me door. Keep saying they come out and do it but been chasing it up for 3 weeks now. Every time phone up they say be out to do it but after 3 weeks chasing up give up. Only thing that stopped me giving 5 stars. Keep saying they come out but 3 weeks to put a number on is disappointing and still waiting.
They fitted me windows and doors now only time been let down by them but nothing major so that why only 4 stars this time. If they do come out I will update review but giving up hope seems only a 2 minute job and only down road. Everything else was good standard and 5 stars.

Since renovating our home we have had many workmen visit, and Allerton Window are easily the best when it comes to renovating! From initial quote, receiving advice, implementing changes along the way and installing our orangery has been an absolute dream. The person I dealt with and his team would schedule the daily plan amongst themselves the installation of electrics, plumbing, RSJ's, flooring, tiling, plastering - they even came back 2 months later to put a light up for me as it didn't arrive on time!
I would simply provide the coffee's I felt completely comfortable leaving the team in my home whilst I ran errands / went to work which meant I didn't have to take as much time off and I would come home to no mess - the tidiest workers I have ever come across. I recommend AW to all my friends and family as it was such a pleasure. We have had 3 separate lots of work done by AW now and looking onto the next project with them. I couldn't rate them highly enough.

Allerton Windows have done a fantastic job on my conservatory. The quality of the products are amazing and it looks great. Nothing was too much trouble for the three blokes who fitted the conservatory. They were very professional, punctual, tidy and they are a credit to Allerton Windows.
Allerton Windows from start to finish provided an excellent service and I wouldn't hesitate at all to recommending them to anyone.
