Questions
Frequently asked questions
How much do uPVC windows cost in Chennai?
The price depends on the window size, the type of opening, the profile series, the glass and the hardware. We measure your openings for free and give you a written quote that lists each of these, so you can compare clearly.
Are uPVC windows better than aluminium or wood in Chennai?
For most Chennai homes, yes. uPVC does not rot or swell in the monsoon like wood, does not corrode in salty sea air like aluminium, and seals tighter to keep out rain, dust and noise.
Which uPVC window is best for a bedroom?
Casement windows seal tightest and give the most breeze. Sliding windows suit rooms where an outward-opening sash would get in the way. We suggest the right one after seeing the room.
How long does it take to make and fit the windows?
After you approve the quote and measurements, we fabricate at our Avadi unit and then fit on site. We confirm the timeline for your project in the quote.
Do you add mosquito mesh and grills?
Yes. Sliding windows can have a sliding mosquito mesh, and we can work with your existing grills or plan new ones during the site visit.

Questions
Frequently asked questions
What is the price of a uPVC sliding door in Chennai?
It depends on the width, height, number of panels, profile series and glass. We measure for free and give a written quote with every item listed.
Can uPVC sliding doors be used for a balcony?
Yes. Sliding doors are the most popular choice for Chennai balconies because they save space and seal well against wind-driven rain.
Will rain come in at the bottom track?
A properly fitted uPVC sliding door has drainage slots and weather seals in the track that carry water back outside. We fit and test these on site.
Can I add a mosquito mesh to a sliding door?
Yes. We can add a sliding mesh shutter on its own track, so you can keep the glass open and insects out.

We plan the fitting with you and keep disruption low. Most of the work is done at our unit, so time on site is short.
