Frequently Asked Questions

My sash windows are stuck. Are they meant to open?

Generally speaking all sash windows are meant to open both top and bottom. Often over time sash windows can become clogged with paint and will stick, but this is something that we can help with. Visit our refurbishment and renovation page for further details.

How can I pay?

You can pay by debit card or BACs or choose to spread the cost using your preferred credit card.

Is it possible to order a door to fit into an existing frame?

No. We will only ever manufacture one of our doors into their own new frame due to the high performance aesthetics we offer.

What kind of disturbance can I expect during installation?

We carry out all work internally and depending on the scale of the works, inevitably there may be some disruption due to noise or dust. However, in advance of our arrival, we ask that you move or cover soft furnishings to minimize this disruption. At the end of each day, your windows will either be completed or left totally secure.

What is the normal delivery period?

Due to demand our lead times can fluctuate but we will provide you with current estimates in the written quotation we provide.

Who will install my new wood windows for me?

Your windows and doors will be installed by our fully employed, trained and experienced installation teams who will treat your home with care and respect throughout the process.

How much deposit do you require?

All we ask is that a deposit of 25% (of the full invoice price) is paid when the order is placed.  We will then require payment of the final balance, which will be invoiced on complete satisfaction of the client at the end of the job.

Do you provide free estimates and visits to my property?

Yes. All estimates are completely free and without obligation.

Do you offer guarantees?

Many traditional timber windows in Britain have lasted for centuries and are still in good working order. We are confident that with minimal maintenance our timber windows and doors will provide a lifetime of high performance. We are proud to endorse this claim with our industry leading guarantees as follows:

  • Purpose made High Performance Window frames
  • The extremely tough and durable preservative and coating characteristics mean we can offer a 30 year guarantee against rot and fungal decay on our complete new windows
  • Installation & workmanship 10 Years
  • Insulating Glass Units in our High Performance Windows 10 years
  • Opaque Factory applied Paint finish 8 years
  • Factory applied stain finish 5 years
  • Ironmongery 5 years
  • In addition to our comprehensive guarantees, as a FENSA registered Company, our clients have access to an additional optional Insurance backed guarantee

How do you compare to a ‘local joiner’?

Your local joiner should be able to make you a reasonable quality casement timber window, although many smaller artisan companies will be unable to replicate the design and technical innovations that a company like ERW who has our own manufacturing facility offer. This is especially true when it comes to the skilled requirements associated with sash windows. More significantly, many joinery companies will not factory finish (i.e. paint) the frames for you, or even glaze them. So the whole process of replacing or refurbishing your windows becomes a major task requiring multi trade co-ordination including a joiner to make the windows; a carpenter to fit them; a painter to decorate them and a glazier to glaze them. From advice, to survey, to manufacture, to installation of fully glazed, factory finished windows, our family run business does it all.

What is secondary glazing?

Secondary glazing involves the installation of new, fully independent secondary window frames on the room side of the existing or primary window. Our secondary glazing is ideal to maintain the external facades of historic, period properties even Grade One and Two listed buildings, while offering better thermal and security performance with reduced noise.

I need new sash windows – shall I replace them or renovate them?

It very much depends on the state of your existing windows, and we make recommendations on a case by case basis. We are unique in that we are a one-stop shop for all your wood window needs, and we offer both sash replacement and / or renovation. For new windows, we design, manufacture in our own facility, and install to the highest standards, a premium range of high performance, custom crafted, vertically sliding timber windows. We also operate a specialist sash refurbishment and renovation division to help you keep the original charm and character, whilst also benefiting from modern developments providing performance and energy efficiency enhancements.

My wood windows need replacing, but the house is a ‘listed building’ – what can I do?

Get in touch with us. During our 30 year in business, we have gained extensive experience of working in listed buildings and within conservation areas. We co-operate closely with many of the North East’s conservation officers and local authorities and are happy to advise on individual cases.

Are timber windows good for the environment?

Timber is one of the most sustainable building materials, and according to Greenpeace: “As long as timber is sourced from properly managed forests…timber windows are by far the best environmental choice” (Greenpeace Briefing: Installing New Windows 1997). ERW only uses timber from sustainable sources. The European Redwood timber used in the production of our windows is harvested from managed forests where the growing period is measured in decades. On average, two trees are planted for every one harvested – as timber usage increases, so too does replanting. Few people realise that the area of land under forestation in Europe is increasing year-on-year and there is more area of European forest now than there was one hundred years ago. We take our environmental responsibilities very seriously.

What is ‘next generation’ double glazing?

The biggest move in thermal efficiency used to be replacing single glazed units with double glazed ones, but now as we all try to preserve energy and save money on bills, product development has been undertaken by our industry that means not all double glazing is the same. We install as standard what is known as ‘next generation’ double glazing consisting low E thermally efficient double glazed units manufactured to EN1279 (part 2) incorporating Super Spacer warm edge technology resulting in windows that are up to 65% warmer at the edge, offer 70% reduced condensation and up to 2Db noise reduction. We also install argon gas filled units that satisfy the demanding EN1279 Part 3.

Will you paint my new wood windows?

Our high performance, new timber windows come factory finished and are available in an extensive range of premium finishes including a market leading wide range of colours and woodstains that enable maintenance periods to be extended. The extremely tough and durable coating characteristics mean we can offer a 30 year guarantee against rot and fungal decay on the coatings and preservatives, 8 years on the coloured and 5 years on the stained. For more on the finishing of windows being refurbished, please follow this link: Window Renovation & Refurbishment.

How often will my wood windows need repainting?

Like all natural materials, wood needs looking after. But our wide range of marketing leading colours and wood stains offer long life expectancy and guarantees. Our extensive range of premium finishes enable maintenance periods to be extended, superb colour retention and redecoration requiring only one coat application. Broadly speaking our coatings last up to 8 years without the need for re-decoration. The precise cycle will depend on a number of environmental factors such as the geographic location of your property and the particular aspect and amount of exposure to the elements.
