Frequently Asked Questions

I live in a conservation area - will I need planning permission to change my windows?

At Heronhurst we offer a range of window systems in PVCu, Aluminium, Composite and real Timber some of which are "conservation grade" specifically designed to look just like the originals, and help alleviate planning difficulties.

How long will my windows last me?

Of course the answer to this varies, and it also depends on location and maintenance
All our products come with comprehensive guarantees which you can read about here
Our products are well engineered, and designed to last the long term - indeed our Aluminium windows come with up to 25 years surface paint warranties, and our timber 25 year anti-rot and fungal warranties
We would say around 30 years is typical of PVCu and Composite, while up to 45 years on Aluminium can be expected, on Timber, subject to suitable regular maintenance, a lifetime
As with most products, certain parts of the window may need repair or replacement over time, without the need to replace the entire window

How long does it take to install my windows?

This depends on the window style, size and material - together with your homes construction and access

But as a general rule of thumb, we would suggest around 4 to 5 windows are installed per day typically, by of our experienced installation teams, and a single door around half a day
Larger items like Bi-Folding Doors can take up to a day in themselves to install, and timber can take up to twice this time to install
Our advisor or Surveyor will be able to give you an accurate timescale for your individual work requirements

Do you install your own windows and doors?

We are happy to offer you your choice of a supply only service or a supply and installation service with a full site survey
We do not install other companies products, and only our own trained installation teams install for us
This helps ensure our customers get a great job every time

What is the best material for my windows and doors?

Well this is a difficult one to answer - because there is a reason that we supply PVCu, Composite, Aluminium and real Timber - it is because they all have their place
So it depends on your needs, your budget, your home, and the look you are trying to create
One of our team will be best placed to advise on an individual bases, because all of these materials can be great - when used in the correct place!

How easy is the access to the Abergavenny Studio Showroom?

We've worked hard to ensure that we can all enjoy what we have on display in our Studio Showroom
We have easy parking onsite, low-level access doors and one flat level throughout the show area, with full disabled access toilet facilities for our guests - plus of course, freshly brewed Teas including Black and Herbals, Coffees including Lattes and Espressos plus filtered, chilled Water - all free for our visitors

Can your windows condensate on the inside?

Our windows do not and cannot cause condensation as they do not generate water
However, depending on the humidity in the room, or outside (for possible external condensation), condensation could fall on a window - although this has been greatly reduced over the years through advancements in insulation
A well ventilated house is essential to help avoid condensation, and improve your wellbeing
Every homeowner should own a hygrometer that measures temperature and relative humidity (RH). The ideal relative humidity for health and comfort is about 40-50%. In the winter months, it may have to be lower than 40% RH to avoid condensation on the windows
You can learn about internal and external condensation on windows and doors here

Why do I have to have a home visit to price my windows or doors?

You don't - but many people find this the easiest way, as we take responsibility for the measuring, can advise on regulations - styles and colours too
But if you prefer not to have a home visit in the first instance, you can either bring your sizes and photos in to the showrooms or click on to our online design and pricing portal - although there are quite a number of options, and not everything can yet be priced online (we currently offer Windows, Door-Stop Composite Doors, Bi-Folding Sliding Doors) - click here to start your quote
In all cases, our sales survey or your measurements are always followed by our professional survey, should you decided to order

What happens to the windows and doors you take out?

We take away anything we take out (unless you ask otherwise) and ensure it's safe disposal using only certified waste management facilities
When we remove PVCu, the vast majority of this is passed through to a recycling company for processing and recycling, the recycled PVCu often used in household appliances, etc.
For Aluminium, the majority is used a scrap, so again re-used for various purposes
We always work hard to minimise our waste, and use responsible disposal methods for the waste we do have

Can I see a visual of my new windows, doors on my house before I make my decisions?

Yes of course, we have recently introduced two new services, our exclusive Truvue Professional Home Visualisation Service - with which we can either super-impose new styles and colours over your existing, or re-create your home in scaled 3D CAD and impose any styles and colours of windows, doors or conservatory you like on it so you can see what the changes look like before you make them. You can learn more about Truvue Professional via this page

Do I need a FENSA Certificate?

When you replace Windows or Doors in the main dwelling of a domestic residence in England and Wales you are legally required to have either Building Regulations Approval or certification from one of the approved bodies such as FENSA, CERTAS or Corgi
We include a FENSA Certificate in every instance where required, and the vast majority of our work work in certified in this way
Conservatories and Glazed Extensions are exempt from this requirement but may still require Building Regulations Approval in certain circumstances, particularly if they have large areas of solid wall or roof or open to the house

Do I need an Insurance Backed Warranty?

If you installation is covered by FENSA then we are obliged to provide an Insurance Backed Warranty in your name and for this to be included in the total project cost

Typically for bungalow or two level homes, we do not need scaffolding to fit your new windows and doors - although on rare occasions, we may and will advise this at point of quotation, should you require it for some unusual reason
Three storey and above often require scaffolding, but not always
Roofline replacement usually does require scaffolding, for the safe working of our teams

We look forward to working with you

I've heard there are good and bad times to buy new windows and doors. Is this true?

Generally speaking no. You should expect to pay the same price year round. It is only unscrupulous sales people and companies who make-up the offers of false limited time discounts that they really offer constantly, but use this to pressure you in to buying before you have had any thinking or comparison time.  Of course, there are a few genuine savings to be had from time to time, but please use your own judgement and only order when everything is right for you - not them!

Why don't you offer Conservatories and Glazed Roofs?

We have decided to concentrate our skills on the products closest to our heart, Windows and Doors - and do them really well

A few are made a little further afield due to necessity of wanting to offer a specific product because of its exceptional quality
