Essential UK Homeowner Tips for Repairs, Extensions and Building Projects
Whether you’re fixing a crack in the slab or dreaming of a new loft bedroom, the right advice can save you time, stress and cash. Below you’ll find clear steps that work for most UK homes, straight from the experts who handle real projects every day.
Spotting and Dealing with Foundation Cracks
First thing’s first – measure the crack. A crack under 2 mm is usually just shrinkage; anything wider could mean movement. Use a simple ruler or a crack gauge, write down the width, and check if it’s growing week by week. If the gap stays the same, you’re probably safe. If it widens, call a structural engineer within a month – it’s better to be sure than to ignore a sign of trouble.
When you do get a professional, ask for a written report that includes the exact size, location and recommended repair method. Common fixes involve epoxy injection for small cracks or underpinning for larger settlement issues. Don’t try cheap DIY cement mixes unless the crack is truly superficial – the right cement mix can hold for decades, the wrong one will crumble.
Planning Extensions and Loft Conversions Without a Hassle
Thinking of adding space? Check the permitted development rules first. In most UK zones you can extend up to 8 m outward from the rear wall without needing planning permission, as long as you stay within 50% of the original house footprint. Anything beyond that needs a council application, which can add weeks to your timeline.
If you’re eyeing a loft conversion, verify headroom. You need at least 2.2 m of clear height for a usable room; roofs with low trusses or dormer windows often fail this test. Also, confirm that the roof structure can bear extra load – a quick consultation with a structural engineer will tell you if you need additional joists.
Budget‑wise, a loft conversion typically runs £1,000–£1,500 per square metre, while a single‑storey rear extension may cost £1,200–£1,800 per square metre depending on finish. Get at least three quotes, and always ask for a breakdown of labour versus materials so you can spot hidden fees.
Beyond extensions, decide if building a brand‑new house is cheaper than buying. In 2025 the average new‑build cost sits around £1,500 per square metre, while existing homes in similar locations often start at a higher price per square foot. Factor in land cost, planning fees and the time value of money – sometimes buying saves you the stress of managing a build.
Finally, keep a simple checklist on hand: measure cracks, verify planning limits, confirm roof load, compare build vs buy costs, and always get written reports. With these steps you’ll avoid costly surprises and keep your project on track.
