New bespoke heritage timber windows
The challenges of heritage windows are no secret to us.
From draughts and rattles to energy inefficiency and sound pollution, we address these issues with a restoration-first approach, ensuring the character of your sash or casement windows is preserved. When restoration isn’t possible, we craft bespoke timber replacements that perfectly replicate the original profile.

Hand-crafted from the finest materials
Our master craftsmen use only the finest timbers best suited to your project, including sapele, redwood, and sustainable Accoya®.
Hardwood
Sourced from slow-growing deciduous trees, hardwoods like sapele, oak, and teak are known for their exceptional strength, durability, and weather resistance. Premium hardwood doors are a long-term investment, offering superior performance for years to come.
Softwood
Derived from faster-growing evergreen trees, softwoods like redwood, cedar, and pine are valued for their strength and flexibility. More cost-effective than hardwoods, softwood doors offer durability with greater design versatility.
Accoya®
Accoya® is a modified pine, enhanced through a process called acetylation. This advanced treatment gives it exceptional resistance to rot, swelling, and harsh climates, with a remarkable 50-year guarantee, ensuring long-lasting performance.

FREQUENTLY ASKED QUESTIONS
How long will the renovation last?
With proper maintenance, our restoration work is designed to last for many years. We also provide a 10 year guarantee for peace of mind.
Do you use sustainable materials?
Whenever possible, we use sustainable and ethically sourced materials.
Are your methods eco-friendly?
Yes! By repairing and upgrading existing windows instead of replacing them, we reduce waste and preserve resources.
What is the Ventrolla Perimeter Sealing System (VPSS)?
The VPSS is our patented draught-proofing system that reduces noise, prevents draughts, and improves energy efficiency while preserving original window character.
I live in a listed building / conservation area – can you work on my windows?
Yes. We often work on listed properties and those within conservation areas and work closely with conservation and planning officers, English Heritage, Historic England, Historic Scotland and Cadw.
Do you need scaffolding?
Where possible we do all work in situ and take the sashes out from the inside of the property. Because of this, we ask that the rooms we will be working in are cleared, and we will dust sheet all furnishings. If scaffolding is necessary, i.e. there is limited access or for larger commercial projects, then we would always discuss this with you in advance of the order being placed.
Can you help with a condensation problem?
The main way you can combat a condensation problem is to further ventilate your home (i.e. open your windows from time to time). The moisture in your home is caused by heating, bodies etc. and it settles on the nearest cold surface – usually your windows. Double Glazing units will be slightly less cold and therefore you may notice slightly less condensation, however, your home will also be better insulated, thus more moisture may be contained within your home.
What kind of wood do you use?
For new joinery we use a hardwood, usually Sapele or Accoya, though we can use other woods if specified. Please ask your Surveyor or see your detailed quotation for further information on the recommended materials.
How does the Ventrolla Perimeter Sealing System improve comfort levels?
The main complaints we hear about are draughty, rattling windows. Our draught proofing system closes the gap around the sashes; eliminating draughts, rattles and reducing dust ingress and heat loss.
Should I replace my existing timber windows with new timber windows?
This is not usually necessary, however, if renovation is not a viable option we can supply complete new timber windows that will match the originals.
How long will my window renovation take?
The time taken will vary depending on the survey result. Typically we work to renovate one window per day, although this can be adjusted to suit your requirements.
