What materials are used for double glazed windows and doors?

uPVC is the most common material for modern double glazed replacement windows, whilst aluminium is another popular choice. If your property is more traditional in its appearance, hardwood timber can also be a fine choice for double glazed windows, and they can be stain finished to match or complement your building’s exterior.

Many of the same materials come into play with doors too, however, composite doors are just as strong and attractive as uPVC, aluminium and wood, so these are generally the ‘big 4’ for doors.

There are lots of door, window and glazing companies in Buckinghamshire. How do I know if a company is highly regarded and reputable?

The best place to start is by checking their testimonials and viewing their case studies. You can then get a good idea on the experience they have and the quality of their products and services. You may also be able to spot a theme running throughout their reviews. For example, many of the customers we’ve helped, loved the fact that we offered free quotes, delivered the agreed work on time and were reliable and honest from the start, the opposite to many pushy salespeople in the industry.

It’s also recommended that you use a company who is registered under the FENSA scheme. A FENSA registered company like 3GS must meet strict criteria and is therefore authorised to supply, install and certificate your windows and doors fully. It is important that they are fully certified at the time of installation because if you were to sell your home in the future, you will be requested to produce the Building Regulations certification prior to sale.

Will I need planning consent for a conservatory?

It depends on the kind of conservatory you’re looking to add to your home. Many conservatories can be built within Permitted Development regulations provided they are within the prescribed size limits. It’s also important to point out that there are different rules for England, Scotland, Wales and Northern Ireland, so your home’s location will also come into play. If you’re unsure, feel free to send us a message or call us and we can advise you on your particular requirements.
