Featured Review Of The Week...

“Allseal Glazing is a very reliable professional company. Their prices are fair, they’re very reliable, they turn up when they say they are. The finished job is excellent. The guys who expertly fitted the new window knew what they were doing. They never made a mess and made sure they left the job nice and clean. I would highly recommend this company.”

 Trustindex verifies that the original source of the review is Google. I had to get glass replaced in a period window in a London Mansions block in a difficult to reach place and I can't recommend All Seal Glazing more. Brilliant job! None of this 'can't do' stuff I've had recently! Gerry has traditional know-how, is a brilliant craftsman and absolute star. Julie was responsive, fast and courteous. These are the 'go to' glazing company, at least in Central London. I'd not reccommend anyone else !!

 Trustindex verifies that the original source of the review is Google. Excellent and efficient service.  Knew what they were doing in cutting a hole to fit a fan in a window whose glass was very thick rather than replacing whole pane. Very good value.

Ansewring Your Questions

FAQs

We you be able to repair my broken window immediately?

In most cases, we carry a range of glass types and sizes to provide immediate repairs. However, the availability of the exact glass match might cause a delay. If the precise glass isn’t immediately accessible, we will secure your property with a temporary board-up and return at the earliest convenience with the appropriate glass for a permanent fix.

How long will it take to arrive in an emergency?

Our response time for an emergency can vary depending on your location. However, we aim to arrive at your location within 30 to 90 minutes of your call. As a well-established glazing company, we can promptly dispatch a team to address your emergency as soon as possible.

How long does it take for you to complete a window installation?

The time required to complete a window installation can vary based on several factors. The complexity of the installation, the type and size of the window, and the accessibility of the area all play a role. In general, a straightforward window installation can take a few hours, while more complex projects may require a day or two. We will provide a more accurate estimate after assessing the specific requirements of your project.
