How Long Will Hardwood Timber Frame Windows Last?
The typical lifespan of timber frame windows is anything between 60 to 80 years. That means that you can enjoy draft free, energy safe high-quality window frames for a long, long time. They are weather resistant and have over two and a half times the lifespan of a plastic window.
Are Hardwood Windows Environmentally-Friendly?
Hardwood windows keep the ozone layer safe too. Timber windows are completely biodegradable, carbon neutral and, should you choose to recycle them, you totally can.

“I honestly didn’t think it was going to make as much difference as it did.”
Jeremy quickly realised our soundproof windows were the best noise pollution prevention solution available. He was impressed by how smoothly the installation went and by the difference the finished windows made to daily life and sleep.
Transform the experience within any property
Would you like to bring a new level of tranquillity to a particular property? Expect to be surprised by the dramatic difference we can make with acoustic soundproofing.
Noise harms. According to the World Health Organisation, those living with noise pollution of over 55dB are likely to suffer health problems. In London, this affects 1.6 million people.
Tranquillity heals. Fitting a property with noise reduction windows can have a hugely healing impact on whoever lives or stays there.
You can reduce noise by up to 45dB. This far outperforms what’s possible with ‘regular’ wooden double glazed sash windows.
Our Process
Step 1 – Initial Enquiry
Before contacting us, please make sure you have certain details to hand. These include: the property location and type, especially if it’s a listed building or in a conservation area, the details of your problem and the kind of windows and glazing you currently have. We will make sure we have enough information to plan an effective initial visit.
Step 2 – Initial Visit (Noise Assessment & Pricing Survey)
An acoustic specialist will talk you through your best options and – using a NTi XL2 Acoustic Analyser – give you an immediate idea of the different noise levels, and advise you on your best options. By agreeing to a Initial Visit there is no obligation to commit to our service; this is an opportunity to understand your needs more clearly.
Step 3 – Quotation & Noise Report
Based on the survey completed during the Initial Visit, our team will email a full costing within 72 hours. We will also provide a valuable Noise Report which explores our problem analysis, the level of noise pollution and our suggested solution. Within another 48 hours, we will follow up with a courtesy call, to ensure everything is clear.
Step 4 – Installation Survey
Once you’ve chosen to proceed with us and paid an initial deposit, we’ll arrange for senior surveyors to visit. By taking accurate to the millimetre measurements, we can assess the best method of installation. We’ll also confirm your various aesthetic preferences (eg – which timber, paint colour and ironmongery), and will then pass your order to our factory.
Step 5 – Manufacture Updates
The manufacturing process takes approximately ten weeks. Every three weeks our customer service team will give you an update so you know how your windows are progressing.
Step 6 – Installation
Two weeks in advance, we’ll provide you with an installation date. For the installation, we use an acoustic foam to enhance the noise reduction. At no point will we leave the property unprotected or exposed; if one window comes out, another goes in. The entire installation will be overseen by a single project manager.
Step 7 – Follow Up
One week after the installation, we will follow up with a courtesy call. This to make sure that everything is to your satisfaction, and to answer any questions you have about making the most of your new windows or doors.

Read our Frequently Asked Questions
What makes Hugo Carter bespoke timber windows different?
Each window is made around the property rather than forced into a standard size or profile. We consider the opening, the age and style of the building, the glazing requirement, the ironmongery and the finish, so the final window feels like it belongs to the home.
Can bespoke timber windows help reduce noise?
Yes. Timber frames, acoustic glazing, specialist seals and careful installation can work together to reduce unwanted noise from roads, rail, aircraft or busy neighbourhoods. The specification depends on the source of the noise and the property itself, which is why the assessment stage matters.
Are timber windows suitable for period homes?
They are often the best choice for period properties because they can be shaped, detailed and finished to respect the original character of the building. Bespoke timber windows are especially useful where standard replacement units would look too modern or out of proportion.
Can you make windows for unusual sizes or shapes?
Yes. Bespoke timber windows can be designed for non-standard openings, including fixed windows, side-hung windows, tilt and turn windows, side swing windows and fully reversible designs. The aim is to solve the practical requirement without compromising the look of the property.
Do you work on listed buildings or conservation area homes?
Yes. Hugo Carter regularly works with homes where the appearance of the windows is sensitive. We can help specify sympathetic timber windows that preserve the character of the property while improving comfort, security and acoustic performance.
How long do hardwood timber windows last?
Well-made hardwood timber windows are built for long service life, especially when they are installed correctly and maintained with care. The exact lifespan depends on exposure, finish and upkeep, but the intention is a durable window that can be repaired and refreshed rather than treated as a disposable product.
Can I choose colours, handles and other details?
Yes. Personalisation is part of the value of a bespoke timber window. Paint or stain colours, glazing bars, handles, fasteners and other ironmongery can be chosen to complement the building and the interior scheme.
What happens before installation?
The process starts with understanding the property, the problem you want to solve and the look you want to achieve. Measurements, product specification and installation details are then checked before the windows are made, helping the fitting stage run smoothly and with minimal disruption.
