Are you an installer looking for a trade window supplier? We’ve created a checklist of 6 important points to remember whilst looking for your new supplier:

1. Experience is everything

Experience is built up over time. If a supplier has been in the market for some time, this means they will have built up a wealth of experience and a more in-depth understanding of how to get the best for each project, which you, as an installer, can take advantage of.

GHW Windows have been supplying the trade with windows, doors and conservatories for almost 30 years, and during that time we’ve supplied windows for thousands of different projects. Partnering with GHW Windows means you can get the best result on any project.

2. The more choice the merrier

Here at GHW Windows, we provide a wide range of window styles and furniture along with multiple window finishes and glazing options. From standard casements to traditional vertical sliders and practical tilt & turn windows, we have everything you need to satisfy almost any customer requirement. In addition to this, we also offer:

3. Customers want quality

4. We all need a helping hand sometimes

If you’re a new installer or you’re just beginning an entirely new project, you might not be sure which products are best for the job. In this scenario, a bit of friendly advice can be invaluable for pointing you in the right direction. This is why our partnered installers have access to impartial advice whenever they need it. We can work with you on budget and advise on specifications.

5. No guarantees, no business
