Common Kitchen Fitting Mistakes and How to Avoid Them

A new kitchen is one of the biggest spends most homeowners make, and the difference between a kitchen that looks good for fifteen years and one that starts to sag, gap or swell within two usually comes down to the fitting, not the units. Most of the problems we are called out to fix are not down to bad products. They come from small shortcuts taken early on that only show themselves once the kitchen is in daily use. Here are the mistakes we see most often, and what a good fitter does differently.

Skipping the survey and setting out

The most expensive mistakes happen before a single unit goes on the wall. Floors in Hampshire's older terraces and Victorian semis are rarely level, walls are seldom square, and chimney breasts or old pipework often sit exactly where the plan shows a tall unit. If nobody checks this properly, you find out halfway through the job, when changes cost time and money.

A careful fitter measures every wall, finds the highest point of the floor, and marks a level datum line around the room before anything is fixed. Every base unit is then set to that line, so the worktop ends up flat and the doors line up. If you want to know what a proper fitting process looks like from start to finish, our kitchen fitting service page explains how we plan each stage.

Poor fixing of wall units

Wall units full of plates and glasses are heavy, and they hang on a surprisingly small number of fixings. The common errors are using the wrong plugs for the wall type, fixing into crumbling lime plaster without reaching sound masonry, or relying on plasterboard alone. Stud walls need noggins or a proper heavy-duty fixing, and that is far easier to arrange before plastering than after.

Signs of a weak fixing include wall units that tilt forward slightly, doors that start to drop out of line, and hairline cracks in the plaster around the hanging rail. If you notice any of these, it is worth having them checked before the problem gets worse.

Rushing the worktops

Worktops are where the quality of a fit is most visible, and where shortcuts are hardest to hide. The mistakes we see most often include:

• Laminate joints that are not tightly clamped or sealed, letting water in and causing the core to swell
• Timber worktops left unoiled on the underside and cut edges, so they cup or split
• Sink and hob cut-outs with raw edges that are never sealed
• No allowance for movement where solid wood meets a wall
• Heavy stone or quartz tops placed on units that were not properly levelled first

Every material has its own rules, and our guide to timber, laminate and quartz worktops covers the care each one needs. Whatever you choose, the cut edges and joints are the weak points, and they should be sealed on the day they are cut.

Forgetting about services and ventilation

Kitchens bring together plumbing, electrics, gas and extraction in a small space, and problems arise when the fitter and the trades are not working to the same plan. Sockets end up behind a fridge housing, isolation valves are buried where nobody can reach them, or the cooker hood is ducted through a long run of flexible pipe that barely moves any air.

Good practice is simple: agree positions for every socket, spur, valve and duct before first fix, keep isolators accessible, and use rigid ducting with as few bends as possible. Gas and electrical work must always be done by suitably qualified and registered trades, and a good kitchen fitter will coordinate with them rather than work around them.

Ignoring the finishing details

Once the units and worktops are in, it is tempting to treat the rest as minor. In practice, the finishing is what makes a kitchen feel properly made. Plinths that are cut short, end panels left with gaps against an uneven wall, cornice joints that do not meet, and doors that are never adjusted after the worktops go on all make a new kitchen look tired from day one.

Scribing panels to the wall, adjusting every hinge so the gaps are even, and fitting plinths with a proper seal at the floor are small jobs, but they take patience. They also protect the units. A plinth sealed at the bottom stops mop water reaching the chipboard legs and carcass bases.

Getting your kitchen fitted properly

Most of these mistakes come down to time. A fitter who is under pressure to finish quickly is more likely to skip the levelling, rush the worktop joints or leave the adjustments for later. Every job differs, so it is always worth asking how a fitter plans to deal with uneven floors, which fixings they will use, and how they will seal the worktops before you agree a start date.
