From my first contact with this company end of November 21, meeting Colin to meeting the fitters Callum and Andy everything went very smoothly. They fitted my door on the worst day possible storm Eunice. Even though they had a nervous customer on their hands they felt confident they could complete the job and they did very successfully. Thank you to Andy and Callum.

Had a livin -room conservatory built on the end of house. Colin & his team did a great job & we are still happy with the job they did. Nothing was too much trouble & I did change plans at my expense! Which meant removing brickwork & starting again! Definitely 5stars from us. Well done BJH. A trustworthy company in these difficult times.

What styles of double glazed windows are popular in Southampton homes?

Southampton properties range from historic Victorian terraces to modern developments, so popular double glazed window styles include sash windows, casement windows and flush-fit uPVC options. BJH Windows offers a full selection of double glazed styles suited to the architectural character of homes across Southampton.

Can double glazing help with traffic noise in central Southampton?

Yes, double glazing is highly effective at reducing external noise, especially in busier areas of Southampton such as Shirley, Portswood or the city centre. We offer acoustic glass specifically designed to reduce noise from outside, whilst further lowering  U-values. By installing high-quality double glazed units, you can significantly reduce traffic noise and enjoy a quieter, more comfortable indoor environment.

Are there energy efficiency grants available for double glazing in Southampton?

Some Southampton homeowners may be eligible for local or national energy efficiency grants, depending on the type of property and current insulation levels. 

How do I maintain double glazing in a coastal area like Southampton?

Homes in Southampton, particularly those near the coast, can be exposed to higher levels of salt and moisture. To maintain double glazing in these conditions, regularly clean the frames with soapy water, inspect seals for wear, and ensure proper drainage around the window. BJH Windows installs corrosion-resistant materials ideal for coastal environments.
