Free quoteWe check every hidden obstacle. When starting a house extension in Sonning Common, homeowners often forget the garden hose tap or the old soakaway pipe buried beneath the lawn. Moving patio slabs, taking down rotten fence panels, and marking the main drain run with chalk will save hours of delay once heavy machinery arrives.
Dust travels everywhere very quickly. Laying heavy plastic sheeting across the hallway carpet and taping door seals prevents cement powder from settling on your furniture when builders haul bricks through your corridor. A simple zip screen over the kitchen entrance keeps the mess contained to the rear garden.

We commence every house extension project with a detailed site survey and exact measurements to comprehend the existing structure and clarify the scope.
Following the assessment, we prepare a clear, itemized quotation along with a contract that outlines timelines, costs, and the comprehensive scope of the house extension work.
We manage all essential planning applications and guarantee compliance with local building regulations prior to starting the house extension construction.
Our crew oversees the structural work and coordinates with specialists as necessary, ensuring the house extension integrates smoothly with the current building.
We finalize all interior and exterior finishes to high standards, conduct a final inspection, and hand over the completed house extension punctually and as promised.
Check the boiler first. Adding extra floor space means adding copper pipes and wall radiators, which will test an older heating unit severely. For any house extension in Sonning Common, checking water pressure gauges in the airing cupboard confirms if the current system can push hot water into fresh external spaces.
Wet systems require careful routing. Running flexible water pipes through thick floor screed demands a separate manifold box tucked inside an under-stairs cupboard, keeping zones distinct so your new rear lounge stays warm without cooking your hallway. Cold spots usually show up when trades rush pipe spacing during the wet pour.


Leaves clog shallow valleys. Flat roof joins collect dead moss from older roof tiles above, especially during autumn storms when downpipes get blocked and spill grey wash over fresh brickwork. Regular clearing of parapet outlets keeps plasterboard dry underneath your new ceiling rafters.
Fine hairline cracks appear naturally. Fresh timber framing dries out over the warm summer months, pulling slightly at corner beads and skimming compound. Filling those minor gaps with flexible decorators caulk before rolling on your emulsion paint stops them reopening.
Rubber perishes over time. The large rubber gaskets around sliding bifold doors need an occasional wipe with silicone spray so they remain supple against driving rain. Completing a house extension in Sonning Common brings comfort, provided external mastic joints around aluminium sills are inspected twice a year for shrinkage.

Ask to see recent sites in nearby areas like Henley on Thames, check how they protect exposed brickwork during downpours, and ask who manages day-to-day trades on site. Clear answers about dust screens, skip placement, and daily site clean-ups prove practical experience.
The team strips ground topsoil, pours concrete footings, and builds blockwork up to damp course level. Roof timbers go on before knocking through into the original building, keeping weather out while electricians run cables through bare stud walls.
Freezing conditions stop mortar and concrete pours, because water inside the wet mix freezes and weakens the structure. Wet weeks require plastic tarpaulins over exposed blockwork, but internal tasks like first-fix wiring continue normally under a watertight roof.
Pitched roofs use clay tiles that match older properties and throw rainwater off instantly, but require deeper structural supports. Flat rubber roofs install faster and allow large roof lanterns, though they require clear drainage gutters to prevent standing water puddles.
