Old shrubs must come down. When carrying out a house extension in Cobham, tradespeople need wide pathways around side gates to wheel away clay and bricks without catching gutters or scraping walls. You might have to sacrifice a boundary hedge or shift garden sheds earlier than planned. Soil mounds swallow lawns fast. Wheelbarrows cut ruts across turf during damp mornings.
Drains hide beneath patios. Digging reveals cracked earthenware sewage lines or forgotten inspection chambers that require diversions before any concrete trucks turn up outside. A mini excavator can snap plastic mains without warning. You should trace water runs with dye tablets before heavy machinery tracks cross the back lawn.

Free quoteOlder mortar breathes quite differently. Fresh footings sink slightly into subsoil while original brick courses sit firmly bedded, which means tying them rigidly together creates diagonal stair-step cracks across plaster. We leave movement joints concealed behind rainwater downpipes to absorb seasonal settling. Unpredictable damp patches appear if lime mortars clash with stiff sand mixes.
New circuits draw power. We frequently discover tired distribution boards stuffed beneath stairs that cannot take induction hobs alongside garden feeds without tripping main breakers. When embarking on your house extension Cobham properties often require heavier supply cables pulled directly from external boundary boxes.

Hidden gullies trap leaves. Oak debris blown from tall boundaries settles behind parapet flashings, backing rainwater up beneath rubber membranes during autumn downpours. Inspect those zinc gutters regularly. Small moss dams will push water straight into your ceiling joists.
Silicone beads dry out. Timber rafters shift against masonry after central heating runs through the winter, cracking perimeter mastics around bifold thresholds. Reapply sealant quickly. Drafts whistle through tiny splits beside kitchen floor tiles.
Thick glazing traps vapor. Cooking steam condenses onto cold aluminium frames unless trickle vents stay cracked open through cold months. With every house extension Cobham homeowners should air out fresh plaster until damp patches fade completely into flat chalky white.

Yes, if your excavation sits close to shared boundaries or cuts into party walls. Surveyors draw notices so both sides agree on wall conditions before shovels hit clay, which stops bitter arguments later over hairline cracks in neighbouring hallway plaster.
Unmapped sewer pipes or soft sand pockets stop work instantly because foundations cannot rest on loose ground without building control revisions. Work halts while structural engineers visit the trench, recalculate beam depths, and deliver updated footing drawings to trades waiting outside.
Mortar freezes when temperatures drop toward zero, halting bricklaying completely until morning frosts melt. Cold spells push schedules back because fresh concrete crumbles if frost penetrates the wet mix, forcing teams to drape thermal quilts across open foundation trenches in Cobham.
Ordering bespoke glazing units before bare openings get measured accurately is a massive blunder. If steel beams sag even slightly under upper brick loads, custom glass sliding doors simply will not slide into the rough brick aperture without costly structural adjustments.
