About Us

JM Joinery Hereford Ltd

JM Joinery is a specialist joinery company based in Callow, just south of Hereford. Since 2000 we’ve built a reputation for straight-talking advice, solid workmanship and joinery that actually fits when it turns up on site.

We design, manufacture and (where required) fit bespoke timber, aluminium and composite products, including:

  • Windows

  • Doors (front, French, bi-fold, stable, gates)

  • Conservatories and garden rooms

  • Staircases

  • Kitchens, cabinets and fitted furniture

Everything is made to order in our own workshop – no flat-pack, no generic imports.

What we do

We cover the full process from design and manufacture through to installation (within our fitting radius) or supply only for trade and self-build customers.

Typical projects include:

  • Domestic homes – replacements, extensions and new builds

  • Barn conversions and heritage-style work

  • Public buildings and commercial projects

  • One-off bespoke items that don’t fit a catalogue description

If it’s joinery and it needs to be done properly, we’re interested.

How we work

We keep things simple and clear:

  1. Initial enquiry
    You send us sizes, photos, drawings or ideas. We’ll tell you what’s realistic, what isn’t, and what we’d recommend.

  2. Itemised quotation
    We price everything clearly so you can see exactly what’s included – no vague “allowances” and no hidden extras.

  3. Design and approval
    Where needed, we provide drawings (including 3D stair visuals) so you can see what you’re getting before we start cutting timber.

  4. Manufacture in our own workshop
    All joinery is built in-house using modern machinery, CNC where appropriate, and properly trained joiners – not just site carpenters “having a go”.

  5. Site fitting or collection

    • Our Certass-registered fitting team installs within our service area, or

    • You/your builder collect as a supply only order from our workshop in Callow.

  6. Aftercare
    We provide customer care information so you know how to look after your windows and doors going forward.

Craft + technology

You’re not just getting “handmade” – you’re getting joinery done with the right tools:

  • Modern CNC machining for accuracy and repeatability

  • Software-based design for windows, doors and stairs

  • Detailed machining data behind the scenes so parts line up the way they should

  • U-value certification available for glazed window and door products

The result: joints are tight, sightlines are correct, and products fit the openings they’re made for.

Materials and sustainability

We only buy timber from suppliers who promote sustainable forest management and can prove their chain of custody. That means:

  • Properly graded hardwoods and softwoods

  • Specialist materials like Accoya from approved sources

  • Timber that’s suitable for purpose – not just whatever is cheapest that week

Good timber in, good joinery out. It’s not complicated.

Standards, accreditations & guarantees

We back up what we do with proper certification and protection:

  • Certass-registered fitting team for windows and doors

  • Insured deposits (through Quality Assured National Warranties) on qualifying window purchases

  • U-value certificates available on glazed window and door products

  • Customer care packs so you know how to operate and maintain your products

This isn’t box-ticking – it’s simply the standard we think should be normal.

The team

JM Joinery isn’t a faceless factory. We’re a local workshop with:

  • Joiners who know how timber behaves over time

  • Fitters who understand how to install joinery so it works in the real world

  • Office support that actually answers the phone and emails

  • Ongoing training as tools, materials and regulations move on

We also invest in apprentices and training so skills stay in the business long term.

Who we work with

  • Homeowners improving or extending their properties

  • Builders and main contractors who need reliable, well-made joinery that turns up right first time

  • Architects and designers who want bespoke solutions rather than compromising a design to fit a standard product

  • Self-builders who need guidance as well as product

If you’re clear about what you want – or you want someone to help you work that out – we’re easy to deal with.
