  • We first used Biggerstaff over 20 years ago and had no hesitating approaching them again to quote for 7 first floor replacement aluminium windows. The quote was very competitive and clearly detailed. Installation was carried out on time and to a very high standard. The installers were very friendly, punctual and tidy and it was encouraging to see the one of same staff members who was here 20 years ago!. Overall an excellent experience. We would have no hesitation recommending Biggerstaff windows.

  • We are extremely happy with the service we got last week. The 2 guys that came to fit were fantastic and even when faced with an issue getting the patio doors through to the back we managed to figure out a solution and with the help of another 2 of your guys got them over the back.
    They were very clean and tidy and making sure what finishes we wanted and any issues they let us know. The finish is brilliant and they make such a difference. So huge thanks to all involved at Biggerstaff, will recommend it to anyone looking for windows.

    Mr Shaw
  • We had new windows installed to the front of our property in 2011 but one of the units started to show signs of condensation, a fact which i reported to the company. After an inspection by one of your employees a new unit was ordered and installed in 2 weeks with no questions concerning liability, etc. being raised. The lady who i spoke to on both my calls to your office could not have been more helpful and courteous and the two men who came to our home were both quick and efficient.
    I shall not hesitate to recommend your company should the opportunity arise in the future but felt that the exceptional service we received should be recorded.

  • Hello Paula, Just a quick note to say a very big thank you for all the work that went into the making of our new conservatory, we are very pleased with the result. Communications with you and Mark were (from this end anyway!!) seamless and timely. The the work rate and the work done by your boys was brilliant, sympathetic and of top quality. Having them on site was a pleasure too, they are all very pleasant guys.
    Having a new room in about 6 weeks flat is surprisingly good, we just have to work out the best way to use it now. Please pass on our thanks to the others…

  • Elliott  and Dan are a credit to your company.  They forged ahead to complete the work in their allocated time, even though this was impacted by pouring rain. There was no corner cutting, nothing over looked and they went out of their way to ensure my electrician was clear about the work needed on the roof vents.  I cannot fault their attitude, competency or commitment to me as their customer.
