SmartFit™ Installation process
To get the true quality and performance out of your new windows it’s vital they’re installed accurately.
The quality of installation is often over looked by homeowners. They see that 2 companies sell the same product therefore the outcome of the installation will be the same. Sadly this is rarely the case.
We’ve created an industry leading installation standard for ourselves called our “SmartFit™” method, which ensures maximum energy efficiency and product longevity.
Below you can read a featured article written about us and our “SmartFit™” method in the popular home improvements website Cosmopolithome.

Frequently Asked Questions
Why should I install uPVC windows?
UPVC windows are extremely durable, energy-efficient, weather-resistant, cost-effective, and pollutant-resistant. Compared to traditional timber, uPVC windows are more economical and aesthetically appealing.
What color options do you have for uPVC windows?
At Smart Homes NI, you get to choose a uPVC window from a varied range of 20 colors. If you want a more modern and contemporary look for your house then choose grey uPVC windows.
Do uPVC windows involve heavy maintenance?
No, uPVC windows require little to no maintenance. You just need to mix a window cleaning solution with water and spray it on the window frames. Then gently wipe it off with a clean and dry cloth. The best thing about uPVC is that it does not corrode, rot, rust, fade, or flake. Thus, you can avoid regular painting of the frames.
Do grey uPVC windows have soundproofing properties?
Yes, our entire range of uPVC windows comes with soundproofing properties. Excellent sealing in both the double-glazed and triple-glazed windows prevents all sorts of noise in the room. We even have specialized acoustic laminated glass for areas of heavy noise e.g. busy roads, railways tracks or airports.
Do you offer a warranty for your uPVC window products?
Yes, we offer a 20-year warranty for uPVC window frames and a 15-year warranty for the glass giving you complete peace of mind for decades.
What is the expected lead time once I place an order?
You can expect a lead time of 8 – 10 weeks, depending on the number of windows and the type of design you have chosen.
