At MKM, our Timber & Joinery offering is built around the needs of professional builders, joiners, roofers and contractors.

Timber at MKM: Expertise You Can Build On

Timber is one of the most versatile materials on site but choosing the right timber matters just as much as availability.

At MKM, we stock a wide range of timber products suitable for a range of applications. More importantly, we back this up with knowledge.

Speak to us, we know what you need. A timber expert is available at branch level, and our staff are trained in timber grading, treatments and end use to help you on your way. Attending regular product and industry training sessions from some of our trusted suppliers mean that we know our products inside and out. Our experts will give you honest advice tailored to your job, not just what’s in stock.

Whether you’re unsure about treated vs untreated timber, load‑bearing requirements, moisture resistance or longevity, your local team are here to help you get it right first time.

 

MDF Skirting: Consistent Quality for a Professional Finish

MDF skirting boards are a go‑to solution for modern builds and refurbishments, and for good reason.

Our MDF skirting is chosen with consistency in mind. Straight lengths, clean edges and uniform profiles mean less time sorting through boards and less material wasted on site. When you’re fitting multiple rooms or working to a tight schedule, that consistency helps keep the job moving and the finish sharp. Sam Mouldings offer a wide range of primed MDF mouldings including skirting boards, architraves and window boards. Whether you are looking for traditional or contemporary profiles, there’s a solution to suit every style.

For installers, MDF skirting offers predictability. It cuts cleanly without knot surprises, fixes easily, and behaves the same way from board to board. That reliability makes it faster to work with and reduces the chance of issues cropping up late in the job. When materials behave as expected, labour runs smoothly, and margins are protected.

MDF skirting is ideal for painted interiors.

The smooth surface takes primer and topcoat evenly, creating crisp lines and a premium look once decorated. There’s no resin bleed, no patchy grain and far less preparation compared to some natural timber alternatives. That’s a big win for decorators and a visible improvement for homeowners and clients.

Where MKM really stands apart is the support behind the product. Our branch teams deal with timber and joinery every day and understand how skirting works alongside architraves, doors and internal joinery. If you need advice on profiles, fixing methods or matching finishes across a project, you’re speaking to people who know the materials and how they’re used on site.

 

Palio Trade by Karndean Flooring: Durable, Practical and Built for Site Conditions

When fitting floors, the pressure is always the same: the product needs to install quickly, perform long term and leave the customer impressed. That’s exactly the thinking behind Palio Trade by Karndean, a luxury vinyl flooring range created specifically for professional installers.

Unlike traditional sheet vinyl, Palio Trade by Karndean comes in pre-cut planks and tiles that accurately replicate the look of real wood and stone, without the drawbacks that come with natural materials.

Durability & value for money

One of the biggest reasons trades choose Palio Trade by Karndean flooring is its durability. The range is fully waterproof, meaning it will not swell, crack or warp when exposed to moisture, making it ideal for kitchens, bathrooms and high traffic areas where spillages and condensation are common. This removes a major risk point when recommending flooring to customers.

A key benefit of Palio Trade flooring is that it is designed for the trade to fit, without the need for specialist tools or training. Ranges such as Palio Core and Palio Rigid use a patented click locking mechanism, allowing installers to fit floors quickly and accurately with minimal downtime.

While Palio Trade by Karndean delivers the performance, we deliver the support. By sourcing Palio Trade flooring through MKM, trades benefit from local branch availability, trained staff who understand flooring applications, and access to advice on choosing the right Palio format for each job, whether that’s rigid core, loose lay or gluedown options.

 

Loft Access Solutions: Safe, Strong and Fit for Purpose

Loft access is often one of the most overlooked elements of a build or refurbishment, but when it’s done poorly it quickly leads to complaints, heat loss and safety concerns. You need loft access solutions that are straightforward to install, compliant, and dependable long after the job is finished. That’s exactly what our range of loft access and loft ladder solutions is designed to deliver, with products suited to domestic, refurbishment and light commercial work.

We supply a wide range of loft ladders suitable for different ceiling heights, opening sizes and usage levels. Timber and metal folding loft ladders from trusted manufacturers such as Fakro, Werner, Dolle and Keylite are designed to provide stable, safe access while remaining easy to operate and discreet when folded away.

We know, reliability is key.

Well-designed loft ladders reduce the risk of movement, misalignment or premature wear, which helps avoid post-installation issues. Whether the requirement is a compact solution for occasional access or a more robust ladder for regular use, our range allows you to match the product to the job, rather than forcing a one size fits all solution.

No more heat loss & draughts

A common customer pain point with loft access is heat loss and draughts caused by poorly sealed or uninsulated hatches. We supply loft hatches and loft access doors, including insulated options, that help maintain the thermal performance of the building envelope while still allowing practical access to the loft space.

Insulated loft access doors reduce heat escaping into the loft, which is particularly important in modern homes where energy efficiency is a key concern. Fitting a properly sealed and insulated hatch helps prevent callbacks linked to draughts, condensation or rising energy bills, protecting both reputation and customer satisfaction.

 

Roof Windows at MKM: Featuring VELUX

VELUX roof windows are widely recognised across the trade as a dependable, installer‑friendly solution. Their design focuses on consistent sizing, integrated flashing systems and strong thermal performance, all of which help reduce risk on site. When fitted correctly, they deliver long‑term peace of mind for both installer and homeowner.

We supply a wide range of VELUX roof windows, including centre pivot, top‑hung and electric or solar‑powered options, allowing trades to match the window type to access requirements, head height and ventilation needs. Whether the job is a loft conversion, extension or like‑for‑like replacement, trades can source the correct window and compatible flashing together in one place.

White Maintenance‑Free Roof Windows: A Clear Winner on Site

One of the most popular options we offer is the VELUX white maintenance‑free roof window, and it’s easy to see why. These windows feature a durable white polyurethane finish that resists moisture, scratches and fading, making them ideal for kitchens, bathrooms, lofts and high‑humidity environments.

There’s no repainting required, no visible joints to trap dirt, and cleaning is as simple as a wipe down. The finish also reflects natural light more effectively than darker frames, helping rooms feel brighter and more spacious, especially in areas where daylight is limited.

For installers, that means fewer future issues to deal with and happier customers long after handover.

Built for Accurate Specification and Easy Replacement

Roof windows often need to align with existing openings, structural constraints or conservation requirements. Our roof window listings clearly show sizes, finishes, opening styles and more, making it easier for trades to select the correct product first time.

VELUX sizing consistency is particularly beneficial for replacement work, where like‑for‑like swaps reduce labour time and disruption. Combined with our knowledgeable branch teams, trades can avoid the guesswork that often leads to costly mistakes.

Correct Flashings, Fewer Problems

Leaks are one of the biggest causes of roof window failure, and incorrect flashing is usually to blame. MKM offers a full range of VELUX flashings, designed to work with different roof coverings including tiles and slates, ensuring a secure, weathertight installation when specified correctly.

By sourcing both the roof window and flashing together through MKM, trades reduce compatibility issues and protect themselves from avoidable callbacks.
