FAQs
Your Questions Answered
We recognise that choosing new windows and doors for your home is a big decision, and one you want to be confident in getting right first time. To help you make that right decision, we’ve coalated a wide selection of some of the many questions we are asked by our customers below. In additon, we would also recommend looking at our Buyer’s Guide page. If we haven’t managed to answer your question here then please do get in contact and we will be more than happy to assist.
I'd like you to give me a quote but I don't want the hard sell or too-good-to-be-true offers.
Rest assured, this is something that we simply don’t do. Ruislip Windows never engage in any dubious sales tactics, nor do we ever attempt to persuade you to sign up there and then. We respect our customers’ privacy at all times, and will never overstay our welcome! In most cases 30-40 minutes is more than adequate to tell you about our products and to take measurements for pricing.
What's the difference between all the different windows and doors that you install? I'm unsure which to go for.
Put simply, we have our standard range of products and then our premium luxury range. Our standard ranges are very good quality products and include our Rehau uPVC windows and doors and our Smarts and Aluk aluminium ranges. Windows and doors from our Residence Collection are designed to replicate traditional wooden windows and contain many additional features you won’t find in a standard uPVC window. We’ve recently introduced the Smarts Aluminium Visoglide range of bifold and sliding doors which are, quite simply stunning.
In addition to our Residence Collection Flush windows, we offer uPVC Flush casement windows from Rehau (the Rio) and Smarts (the Heritage). Our Evoke Aluminium windows and doors are also beautifully flush. For technical specifications, please talk to us and we will gladly advise you on all our ranges, or check out our product brochures which will give you more information. uPVC is still the biggest seller, but aluminium is gaining in popularity, and is usually first choice for architectural projects.
I don't want white "plastic looking" windows, I'd like something different.
You’ll be pleased to hear you don’t have to! All of our uPVC windows are available in several different colours and woodgrain foils. You can even have dual colours, so a colour on the outside and white on the inside. Aluminium profiles can be powder-coated to any RAL colour – that gives you a choice of hundreds of different colour options. Our Residence Collection, Rehau Rio Flush and Deceuninck Heritage flush windows have such authentic looking woodgrain foils it’s hard to tell they’re not wood.
I've had new windows installed and I've recently noticed a lot of condensation in the morning - it's like they're steamed up! What's going on? I thought new double glazing was meant to stop condensation?
Rest assured, this is quite normal with high performing energy efficient glass sealed units (the outer pane is colder as a result of heat being retained inside the home). For a short period during spring and autumn, you may experience external condensation on your windows. Once the window pane warms up, the moisture evaporates and the condensation clears. The air movement from a gentle breeze can also help to clear it. You will find that as the weather warms (spring) or cools (autumn) the phenomenon simply disappears.
I don't want to replace my existing windows but I would like to improve on their thermal efficiency. I live by a busy main road and would also like to reduce the amount of noise if possible.
All our replacement windows and doors will reduce outside noise levels, particularly if you choose our special acoustic glass. However if you don’t want to replace your existing windows because of heritage features such as stained glass or leads, then secondary glazing is an alternative to consider. It will improve the thermal quality of your windows and reduces outside noise levels considerably (when closed).
What is an "Equal Sightline"?
When manufacturing most modern replacement windows it is normal for there to be smaller areas of glass wherever there are openings (vents) fitted. Where the frames are fixed the glass area will be larger. This creates an “unequal” site line.
Traditional wooden windows would usually have equal sight lines (you can’t tell from the outside which windows open and which don’t). This is particularly the case with bay windows. Fitting “dummy vents” into the frames will create what is known as an “equal” sight line.
Whilst equal sight lines are not for everybody; indeed some will not like the somewhat bulkier appearance of the window, there is no doubt that for some types of property this will be the preferred option. It is also a very good alternative with Georgian and leaded window designs as it allows you to have rectangles or squares that are equal in size.
Note: All the sightlines in our Heritage ranges such as the Residence Collection, Deceuninck Flush and Rehau Rio Flush are perfectly equal, thus replicating a traditional flush timber window.
Can I see some of your previous work and talk to your customers?
Yes of course. Please contact us and we’ll be glad to help. Please also read what our customers have said about us on our testimonials page.
I've always thought that the big national companies do a better product; is this true?
Not necessarily no. We install tried and tested products from top manufacturers such as Rehau, Kömmerling, Residence, Smarts, Aluk and Reynaers. Just because we’re “small and local” doesn’t mean our products are “small”, far from it! In fact with a small well established local company such as us, you get the best of both worlds. A top quality product installed by someone who really knows the product and cares about their customer – this can make all the difference, particularly where the fitting and the aftersales are concerned. Plus, in a WHICH? survey, small independent installers outperformed the large nationals every time.
What are Window Energy Ratings?
Window Energy Ratings (known as WER) are a guide to the energy performance of your windows. There are two main schemes run by the British Fenestration Ratings Council (BFRC) and the British Standards Institure (BSI). The window energy rating scheme checks all the components to ensure the final window achieves the energy efficient standard claimed. This means that you just need to look for the A-G ratings and remember the higher the energy rating, the more energy efficient it is. All windows installed by us (both aluminium and uPVC) achieve at least an A rating, and often higher.
Find out more about window evergy ratings at the BRFC website and the BSI website >>
What happens if something goes wrong after my windows are fitted?
Our commitment to our customers doesn’t end once your installation is complete. We have our own service engineer to tackle any problems you may experience. General repairs will usually be undertaken within a few working days. Urgent repairs on the same day. And what’s more, this service is not chargeable within your guarantee period. Our aftersales service is something we are particularly proud of and we receive many positive reviews about this.
I'm very concerned about security. Can you guarantee the security of your products?
We only install tried and tested products by top manufacturers. All products have to go through rigorous testing procedures and the industry is constantly developing and evolving their product specification. Initiatives such as “Secured by Design” also mean that specific products have been independently tested and certified as reaching a certain standard. The security standards of each product we install are detailed in the individual product brochures.
What is Secured by Design?
Secured by Design focuses on crime prevention at the design, layout and construction stages of homes and commercial premises and promotes the use of security standards for a wide range of applications and products. Established in 1989, Secured by Design is owned by the Association of Chief Police Officers (ACPO). The company operates a licensing scheme currently including more than 350 member companies who are entitled to use the Secured by Design logo on products that have passed the tests specified by ACPO Secured by Design. Many of the products that we install have been approved by the Secured by Design initiative.
NOTE: Not all products manufactured by SBD member companies and installed by ourselves are SBD products. Sometimes you may need to select additional extra features for a product to become SBD accredited. Talk to us if you’re unsure and want to know more. Visit the Secured by Design website for further details.
Who are QANW?
Quality Assured National Warranties administer our insurance-backed guarantees and are one of the UK’s leading providers of insurance backed guarantees and deposit protection insurance. The consumer protection offered by QANW comes in the form of an insurance policy, issued directly by QANW to the customer, whenever work is done by a participating contractor. This policy is designed to protect the homeowner against defects in the insured works, where the original installer has ceased trading and is unable to honour their own guarantee. Additionally you will have deposit protection, so if you have paid your deposit and the contractor goes out of business before your installation is completed, your deposit is protected. These insurance schemes are underwritten by Guarantee Protection Insurance Ltd, which is a UK based, FSA registered insurer. The insurer is a member of both the Financial Ombudsman Service and the Financial Services Compensation Scheme, meaning that householders have very strong rights to recourse in the unlikely event that things go wrong. Please watch our helpful short video on our Brochures and Videos page for more information.
How long will I have to wait for my windows to be fitted?
Usually no more than 3-4 weeks (yes, you read that right!), but it does depend on the time of year and how busy our workload is and if you’ve ordered anything usual or bespoke. If you’ve got tight deadlines to meet, speak to us, as we will always do our best to work within these. We will always make it clear at the time of our quotation how long you will be expected to wait between placing the order and installation.
Do you offer heat reflective glass?
Yes, we can fit heat reflective glass, also known as solar control glass, to windows, doors, conservatory roofs and roof lanterns. It has a fine metallic coating that bounces most of the sun’s heat back outside while the daylight still comes through as normal, so a south-facing room or a big set of bi-folds stays comfortable on a hot day. Not every window needs it, so give us a ring and we will tell you which of yours would benefit.

Had to get French doors replaced at my mother in law’s after a break in - asked Ruislip Windows & Doors for a quote after we were impressed with other works they had completed for us. Once again they didn’t disappoint - Tom (their fitter) did a superb job. The new doors match the old ones & look fantastic. The securely system is also a lot better. We really couldn’t have asked for better service & at such a good price. We will certainly be back when our next glazing job comes around

I recently had my bathroom window fitted by this company and couldn't be happier with the service. From the initial enquiry, they were incredibly quick to respond and kept me informed throughout the process.
The quality of the window is excellent and has made a huge difference to the room. The fitters were professional, friendly, and extremely polite. They completed the installation to a very high standard, worked efficiently, and left everything clean and tidy afterwards.
I would highly recommend this company to anyone looking for new windows or doors and I will definitely be using them again in the future.

A very good Company to work with. They respond rapidly to requests; their people are professional, polite and clearly very competent. Their products are of excellent quality; well-designed and at decent prices. From intial contact to delivery and fitting was rapid. Their fitters/tradesmen were on time (early--- very early, in fact) and in doing what is quite a messy job they protected all flooring and furniture during the fitting process and left the place very clean and tidy. We were delighted with the final result. (fitting bifold balcony doors). All round, quality products, quality service, quality fitting and qualitypeople at a good price. Would definitely use them again.

They offer top quality, multipoint locking windows and doors. Their prices are good and we were invited to their showroom to view the various options. We had Fernando and Casio to fit them and they did a superb job, worked long days and the finish was so neat there was no need for redecoration. Very happy.

We recently had all the windows and porch doors in our home replaced by Ruislip Windows, and we couldn’t be happier with the experience from start to finish.
From the initial quotation through to the measuring and final installation, everything was handled smoothly and professionally. The whole process felt well organised, and we were kept informed every step of the way.
A special mention has to go to Ross and Lee, the fitters, who were absolutely fantastic. They were professional, friendly, and incredibly hardworking. Their attention to detail was outstanding, and nothing was ever too much trouble—they took real care to make sure everything was completed to the highest standard.
The end result looks amazing, and the quality of the workmanship really shows. We would not hesitate to recommend Ruislip Windows to anyone looking for excellent service and top-quality installation.

Any small issues were fixed immediately with no questions asked (they replaced a scratched internal pane and buffed a mark on the frame straight away).

We contacted Ruislip Windows about replacing our porch and was pleased to find they could fit new front, side panels and trim and use the original roof and frame. The whole process from Mark visiting to discuss what needed doing to Rob and Ryan fitting the new parts was excellent, all old parts were removed same day and everything was kept clean and tidy. Rob's eye for the finishing details was second to none.
We have used Ruislip Windows before and would recommend them to anyone that asked.
Thank you to everyone we spoke to, we are well pleased with the final item.

The surveyor was very helpful when he came to measure up and advised us on the types of installations available and when we could expect the installation of our doors and windows.
We received a text, within the period advised by the surveyor, asking us when would be a convenient time for the installation.
On the day of the installation the first fitter arrived early in the morning and started removing the old windows and doors. Soon after a second van arrived with the replacement doors and windows and installation commenced. The men worked non stop and completed mid-afternoon. The surrounds of doors and windows were repaired where necessary. The old fittings were removed and all the rubbish swept up and cleared away.
We were shown how the locks and the internal blinds worked.
Overall we are very satisfied with the new doors and windows and the workmanship of the fitters. We would certainly recommend Ruislip Windows and Doors Ltd to anyone.
