We were getting a partially built porch completed with the roofing, doors, windows and a new fascia

We were getting a partially built porch completed with the roofing, doors, windows and a new fascia and guttering - the team coming to do the entire job we're prompt, respectful and tidy. Honestly couldn't have asked for a more perfect job!

Challenges with Installation

I used the service twice recently; the first experience was excellent with quick installation. The second installation turned out to be more complex. The company proceeded with measurements that didn’t account for potential issues until the old bay window was removed. While the fitters were great, better assessment beforehand would have been beneficial. Once installed, the window looked great, but there were some unexpected holes left that needed patching. Overall, I appreciate the service but hope for more thorough diligence in the future.

Exceptional Experience

After using the service in 2018 for our lean-to upgrade, we returned due to their excellent professionalism. Once again, we had a wonderful experience from start to finish, with competitive pricing. Our new windows were installed in just two weeks, which was impressive. The fitters were exceptional and provided top-notch customer service with great attention to detail!

Reliable Window and Door Service

I have utilized the service twice over the past 12 years, and they consistently provide a great experience from the initial quote to the final installation. The sales team is honest and knowledgeable, offering friendly advice without being pushy. We were very pleased with our installation and would not hesitate to recommend them or use them again.

Thrilled with My New Door

I was guided by reviews when choosing a door manufacturer, and I’m glad I was! My new doors look and function perfectly. The communication was clear, friendly, and quick, and the service was truly excellent. As someone with high standards, I can say that everything went smoothly, and the price-to-quality ratio is exceptional. I highly recommend this service.

Excellent After-Sales Support

I reached out to the company’s after-sales service via email regarding a sticking door latch. The technician responded almost immediately and provided a straightforward solution that resolved my issue. There was no sales pitch or pressure to buy something new—just honest, free advice. This level of service is commendable.

Disappointing Experience

Unfortunately, I had a poor experience with the service. A sales representative provided a free quote but also signed me up for a loan without my consent. We had clearly stated that we would pay upfront if we chose their service. The sales tactics felt manipulative, and I had to make it clear that I did not approve of the finance agreement.
