Beyond our manufacturing and installation service, we invite architects, trade, homeowners and project managers to partner with us through our bespoke joinery manufacture and supply-only service. Here, our advanced expertise in creating premium, sustainably sourced timber windows and doors enables property owners, tradespeople, designers, builders, and DIYers to install them themselves. Our supply-only service of custom-crafted wooden windows and doors will complement your build – whether your project is a renovation, an extension, or a new self-build. With an extensive range of bespoke timber products available, our knowledgeable team is here to partner with you and handcraft perfect solutions for your project.
Everything is crafted to your exact specifications; period-authentic designs, restoration work, contemporary profiles & architectural features.
Decades-long expertise in exceptional timber production to overcome any challenge and complex design.
Whether your project includes restoring a leaking rooflight in a heritage property or designing a grand extension with a feature roof lantern, we will manufacture and supply a custom-made roof lantern to meet your exact standards. Handcrafted and prefinished, carefully in line with your plans, our supply-only timber roof lanterns and roof windows deliver the perfect blend of luxury, traditional craftsmanship, and modern performance.
Let's Talk
As a supply-only specialist, we work closely with installers and builders across Yorkshire to deliver precision-engineered timber windows and doors that meet the specific thermal and structural requirements of current-day projects, ensuring your clients enjoy a comfortable, energy-efficient space year-round.
Our timber of choice is Accoya, which has been specially treated and resists rot, won’t warp or twist, and requires very little maintenance compared to traditional timber – making it an excellent choice for any property. Accoya carries a manufacturer-backed guarantee of 50 years against rot specifically. Our DHW 5-year warranty is in addition to the manufacturer-backed guarantee as stated above.

Partner with us through our supply-and-fit or supply-only service! Access locally made, timber-manufactured products of the highest quality, with the peace of mind that comes with distinguished joinery work built to last and covered by our *DHW 5-year craftsmanship guarantee.
* Subject to DHW Terms and Conditions of Supply
**Note that any damage sustained to the windows/ doors or other products during fitting that affects the structural integrity of the window /paint system will need to be rectified before the 5-year warranty will be valid. This may incur costs at DHW’s discretion, depending on the severity of the damage.
Our Workshop in the heart of Yorkshire is able to handle even the largest scale projects.
DHW began at a Yorkshire workbench in 1989, shaped by a simple belief: craftsmanship matters.
Because we design and manufacture everything ourselves, nothing leaves our workshop without care, precision and pride. No production lines. No off-the-shelf shortcuts.
Just skilled joiners, quality timber, and work done properly — built to last for generations.
