Double Glazing Southend-On-Sea

Double Glazed Windows

Flush Sash Windows

When you are living in a period or listed property, or you are living within a protected area, it can be a hassle finding windows that can be approved for planning permission. However, our flush sash windows are ideal for these types of properties and are often passed through planning permission without objection. You can even request a heritage specification during the design process if you would like.

Our  thermally efficient double glazing easily achieves U-Values of 1.3, making your Southend-on-Sea property warmer and reducing your carbon footprint.

Sliding Sash Windows

If you are looking for a more traditional or heritage look when it comes to the design of your windows, then our sliding sash windows can provide that whilst not sacrificing any of its modern perks of design and technology. With a slimline design, its aesthetic can perfectly blend in with a home’s appearance and complement pre-existing features. Depending on the specifications you choose, including materials, you can have your windows achieve a U-value of 1.0, which is 100% more efficient than the limiting U-value for windows. Internal beading and a multi-point locking system are included as standard to strengthen your windows against forced entry, protecting you, your family and your personal belongings from potential intruders.

We offer a wide collection of different styles, including sliding sash, which allows you to be able to find the right design that will perfectly complement your properties style. Our heritage range of sash windows can tilt inwards and come with ovolo beading, both of which ensures of year-round protection for your home in Southend-on-Sea.

However, if you are looking for a more traditional look, we also offer windows that can perfectly mimic the look of timber frames. Timber is a very sought after look, but its needed upkeep can cause a lot of hassle to homeowners trying to keep its high end appearance consistent. Our frames do not suffer from natural wear and tear and provide a brand-new appearance for years on end with only occasional cleaning needed.

Aluminium Windows

While uPVC is the more popular and recognisable choice when it comes to double glazing, it is not the only option available to you. Sturdy and hardwearing against even the harshest weather, our aluminium windows aren’t susceptible to rust, rot, discolouration or warping, unlike other similar materials, including timber. With finer sightlines than uPVC, your aluminium windows are also highly thermally efficient, long lasting and provide outstanding soundproofing to make your home quiet, warm and secure.

We had a Solidor front door fitted and couldn’t be happier with the door or the service. The fitters were reliable, clean & tidy. Would highly recommend.

My new windows are fab, already had compliments. The whole process was easy and problem free. The installation was excellent, K&V were professional, polite and funny. What could have been very stressful was made easier by them. Thank you!
Nina Batty - June 2023
Very Professional from start to finish. From measuring up and ordering our doors to the fitting was about 4 weeks. Vince & mate came round and fitted the doors in a morning, we just provided the tea. Very competitive price as well as a 10 year guarantee! All in all, a very good service.

This is the second time I have used Seemore Glass, the first time to have a Front door fitted and this time Bi-fold garden doors.
