DOUBLE GLAZING GUILDFORD

Double Glazing Windows and Doors in Guildford

Raven Bespoke Improvements has operated in Guildford for a number of years, and as you may already know, there are hundreds of houses in the area with old and inefficient windows. These are most often single glazed windows, but there are also plenty of examples of double-glazed windows which are over two decades old. These can be replaced with new double glazing which is up to ten times more energy-efficient.

We specialise in double glazing, and in particular, the modernisation and replacement of older units. We can recommend the right windows the first time around on consultation which comes with no obligation to buy. We’re in a great position to help with your double glazing in Guildford because we have close links to a variety of leading manufacturers who specialise in producing windows with the latest technologies to the latest industry standards.

Double Glazing Options

The great thing about double glazing is there’s a product to suit every budget. Even economy windows are good nowadays, with a U-value of around 2.0. Better double glazing in Guildford can have a U-value of lower than 1.5. Ultimately, the best double glazing for you will depend on your budget and what you want from your windows. We use products from brands such as VEKA and EUROCELL. We only deal in quality products.

Double glazing is available for sash windows, casement windows, bay windows, sidelights, jalousie windows and more. Sometimes, it’s possible to convert old timber windows from single to double glazing but the cost is high and the process sometimes impossible. It’s often easier to get single glazed windows replaced with new double-glazed units, although you will probably need to attain listed building consent if your building is listed.

UPVC DOUBLE GLAZING WINDOWS

Raven Improvements in Guildford

We’ve worked on a wide variety of projects in Guildford, from replacing a solid external house wall with a panoramic bi-folding door near Pewley Down, to fitting out a converted mill with 26 new double-glazed sash windows. We know the area well and regularly travel through on the A3. We are based in the south ourselves and love nothing more than an outing close to Guildford Castle or further down the River Wey.

ENERGY AND EFFICIENCY

Choosing the right windows 

You can have your windows with a timber, UPVC or aluminium frame. The choice is yours, with timber being paintable any colour and UPVC available in grey or white (brown is also available, but it’s not very popular).

Different types of glass are available. We recommend glazing filled with argon gas with a warm edge spacer. The gas cavity acts as an insulator and barrier from heat loss. It’s much better than air and never needs replacing.

You’ll come across double glazing in Guildford with different U-values. The specification for domestic buildings in Part L1A h for windows is 1.4 W/m²K. A good rule of thumb is modern double glazing generally starts with a U-value of 2.4. A lower number is better.

Windows with high-quality glass, such as Pilkington glass, can have a U-value as low as 1.3 which is really good but any U-Value below 2.0 is fine. If you want a better U-value, you might like to consider triple glazing, which can have a U-value as low as 0.7.

David fitted new windows and French doors for us. He is without doubt the best... tradesman we’ve ever used and we would highly recommend him to anyone. Punctual, professional, efficient and takes pride in his work. We were happy to leave David and his excellent team working in our house when we were out. Everything was left spotlessly clean and the work was done to a very highly standard very quickly. David fixed a broken gutter for no extra charge and readjusted a door, neither of which was part of the agreed job. Thanks a lot David for a flawless five-star service just before Christmas!read more

Hired David and his team on a repair and finishing job after having been let... down by another contractor. His approach was superb, professional, polite and very responsive. His price is higher than some, but he is well worth the extra investment. The value for money you get from him and his experience is exceptional and I have no regrets about using him or the work provided. This was not a straight forward job but David made it feel that way. Highly recommended.read more

One word: Superb. Thank you David for a brilliant job on replacing my... conservatory roof. No task was too big or small. David even took it upon himself to fix a broken gutter at no extra charge. The whole job was done at a very good price. Very clear communication, tidy and very professional at all time. I already have recommended him to my brother-in law and will continue to do so to others. Thank you David!read more

David is the best and most reliable contractor I have ever met. He converted... our courtyard into a conservatory. This was done at a very high standard. It looks amazing and is completely waterproof. He came across a lot of unforeseen problems in the process, e.g. had to clear a drain, move an extractor fan, level the ground area etc- which he attended to effortlessly as part of the job. He also assisted us with many ancillary and unrelated matters, e.g. putting my clock up against the wall, remove old window frames, liaising with another contractor on damp issues elsewhere in the house- all without charging extra as other contractors would do. He is super professional in the execution of his work and regularly updated us as to where we are in the process. He also has wonderful bedside manners, a superb sense of humour, and a humane touch. We always felt that we are in such good and honest hands. I would highly recommend him- we will never be using anybody else at our home again. Well done David and thank you so much for your help.read more

David texted me the morning after I had advertised the work. He turned up the... same day. As I was describing the work that needs doing: he kept saying, Yes, I can fix that ( French sliding door), Yes, I can fix that too ( conservatory door), yes I can replace that as well ( conservatory roof). He came back to me with the quote within 1 hour. Reasonable cost. And, yes he did all the work with professionalism. I must admit I had few other window-doors and conservatory specialists...All I can say is that they should go to David for some training. David is miles ahead of anyone I had around, in every aspect. I strongly recommend David - do not waste time with anyone else if Dave is available...and boy, he is not only smart and experienced but hard working and kind,too. Well done Dave, God Bless and keep up the good work!read more
