Cupboard installation

A skilled carpenter ensures that units are perfectly level, even in older British properties where walls are rarely straight. This guide covers everything from typical labour rates to the technical details of a high-quality installation.

What Does the Work Involve?

• Site Survey: Measuring the space, checking for floor levels, and identifying the location of pipes or electrical cables.
• Preparation: Removing existing carcasses, skirting boards, or coving to allow for a flush fit.
• Assembly & Positioning: Building carcasses and dry-fitting them to ensure the layout works with the room's proportions.
• Scribing: Cutting the side panels or filler pieces to follow the exact contour of uneven walls or floors.
• Fixing: Securing units to wall studs or using heavy-duty masonry fixings to ensure they can handle weight.
• Hardware Fitting: Installing doors, drawer runners, handles, and soft-close mechanisms.
• Finishing: Adjusting hinges for perfect alignment and applying mastic or trim to close any small gaps.

Typical Costs

Total costs are primarily driven by the complexity of the "scribe"—the time taken to fit square units against wonky walls. Bespoke joinery using solid hardwoods or high-grade MDF will significantly increase material costs compared to standard chipboard carcasses.

How Long Does It Take?

• Single free-standing unit: 2–4 hours for assembly and basic wall-tethering.
• Pair of alcove cupboards: 1.5–2 days, including scribing and fitting doors.
• Full-height fitted wardrobe: 2–4 days depending on internal shelving and lighting.
• Under-stairs storage: 1–2 days due to complex angles and custom door cuts.

DIY or Professional?

Assembling a basic free-standing wardrobe is a manageable DIY task for many. However, "fitted" furniture requires specialist tools like track saws, digital levels, and jigs for hinge boring.

If your walls are not perfectly vertical (common in Victorian or Edwardian terraces), a professional carpenter is essential to avoid unsightly gaps and binding doors.

Note that if your cupboard installation involves moving sockets or adding integrated LED lighting, you must use a qualified electrician to comply with Part P Building Regulations.

Choosing the Right Tradesperson

• Check Qualifications: Look for City & Guilds or NVQ Level 2/3 in Site Carpentry or Architectural Joinery.
• View a Portfolio: Ask for photos of "scribed" edges; a good carpenter will be proud of how their units meet the wall.
• Insurance: Ensure they hold Public Liability Insurance (minimum £1 million).

3 Questions to Ask:

• "Do you use a dust extraction system while cutting indoors?"
• "Will the quote include the cost of all ironmongery (hinges and handles)?"
• "How do you handle awkward obstructions like gas meters or fuse boxes?"

UK Regulations

• Part P (Electrical Safety): Applies if the cupboard includes integrated lighting or relocated sockets.
• British Standard BS 6222: Relates to the durability and safety of fitted furniture.
• Fire Safety: If installing cupboards in a communal hallway or near a fire escape route, specific material ratings may apply.

Common Problems

• Hinges Dropping: Often caused by using cheap, thin carcasses that cannot hold the weight of heavy doors.
• Moisture Issues: Installing cupboards against damp external walls without an airflow gap can lead to mould growth inside the unit.
• Floor Compression: Heavy wardrobes can cause floorboards to creak or dip; a pro will reinforce the base if necessary.
• Poor Alignment: If the carcass isn't perfectly level, drawers will slide open on their own and doors will never hang straight.

Frequently Asked Questions

Do I need to remove my skirting boards before the carpenter arrives?

It depends on the finish you want. Most professionals prefer to remove the skirting so the cupboard sits flush against the wall, but they can also "scribe" the cupboard base around the existing skirting if requested.

Can a carpenter install IKEA or flat-pack cupboards?

Yes, many carpenters offer a flat-pack assembly service. They often add value by securing them more robustly than the standard instructions suggest and adding custom filler panels for a "built-in" look.

What is the difference between MDF and solid wood for cupboards?

MDF is more stable and won't warp with temperature changes, making it ideal for painted finishes. Solid wood offers a premium natural look but is more expensive and requires more maintenance.

Should I paint the cupboards before or after installation?

It is usually best to prime the components before installation and apply the final topcoats once the unit is fitted. This allows the carpenter to fill screw holes and sand joints for a seamless finish.

How much weight can a wall-mounted cupboard hold?

This depends on the wall type. A cupboard fixed into solid brick can hold significantly more than one fixed into plasterboard. A professional will use specific anchors (like Geofix or toggle bolts) to ensure safety.
