Highly Recommended
We’ve built up a positive reputation as a leading home improvement company in Northamptonshire since we started trading over 40 years ago from our Wellingborough showroom. Many of our customers are recommending our home improvement installations to others, and we have even received awards!
T&K Home Improvements differ from other double glazing installers in the Northamptonshire region through our family connection with Emplas. As part of the larger Emplas Group, we are uniquely positioned in that we are directly connected to our core upvc and aluminium manufacturer, rather than juggling various middlemen and supply companies. This will result in reliable delivery and installation times.
We can take an increased role in quality control thanks to in-house manufacturing and can offer efficient and accurate lead times that are reliant on fewer parties. There’s no chance that too many cooks will spoil the broth with our double glazing, triple glazing, or uPVC windows and Aluminium doors!

Testimonials
Happy Customers
We would fully recommend both Greg and T&K based on our experience
From the survey stage, receiving a quotation and final installation, the processes were all straight forward and of course we are more than pleased with the quality of the product and just as important the workmanship and politeness of the fitters.
Would not hesitate to recommend T & K to family and friends
