Protect your investment in a Mendip Hills new build - our inspectors catch defects before they become your problem








BS25 covers Winscombe, Sandford, Churchill and Shipham - a cluster of North Somerset villages on the northern edge of the Mendip Hills. Average sold prices here reached £497,093 in 2025, with 4-bed detached homes at Stonewood Homes' Meadow Gate development in Sandford listed from £659,950. When you're spending that kind of money on a new build in a protected landscape, a professional snagging survey is the most effective quality check available to you.
Our inspectors assess 400+ items across your new home, from roof drainage and external brickwork to internal joinery, plumbing pressure and electrical fittings. In BS25, we pay particular attention to how drainage and groundworks have been specified - Carboniferous Limestone beneath the Mendips creates karst conditions where surface and groundwater behave differently to clay-based ground elsewhere. Adequate drainage specification matters here.
On average, our inspectors find 40-60 snags in a newly completed home. We document every defect with photographs and written evidence, then hand you a report your developer is obliged to address before legal completion. Book before you exchange contracts and we can attend on completion day.

Mendip Hills Carboniferous Limestone - specialist drainage consideration
The same Carboniferous Limestone that carved Cheddar Gorge and Wookey Hole runs directly beneath new homes in BS25. The British Geological Survey names the Mendip Hills as one of England's primary karst and sinkhole risk areas - limestone dissolves along joints and fissures, creating underground voids and drainage patterns that differ fundamentally from clay-based ground. For new build buyers, this means drainage specification, foundation design and groundwork quality all carry extra significance. Our inspectors check that drainage outlets are unobstructed, that perimeter drainage is correctly installed, and that any visible ground-level settlement or cracking is documented. We also note Radon - the Mendip Hills sit in a PHE-designated Radon Affected Area due to uranium content in the limestone. New builds in BS25 should have a radon barrier membrane installed as standard; we verify this is present and correctly sealed.
Stonewood Homes' Meadow Gate development in Sandford launched in December 2024 and is currently selling 3 and 4-bed homes from £395,000. Stonewood is a well-regarded regional housebuilder, but quality varies by plot, subcontractor, and stage of build. Our inspectors attend the completed property - not the show home - and work through every accessible area systematically.

Estimated from HMLR sold data patterns and North Somerset rural area profiles. BS25 has significantly higher detached share than the national average of ~23%.
Prices shown are starting prices. Final quote depends on property size, location and access. Book before legal completion for best results.
North Somerset planning controls mean new build sites in BS25 are rare. Meadow Gate at 49 homes is a significant local event - developers, subcontractors and on-site teams are all working under pressure to meet delivery targets. That commercial pressure is the primary driver of snags. When finishing teams are working fast across multiple plots simultaneously, quality control suffers on repetitive tasks like silicon bead application, skirtings, and external joinery sealing.
The AONB and conservation area context also means that any external defects - cracked render, poorly pointed stonework on feature elements, misaligned boundary walls - will be more visible and harder to live with in a village setting than on an urban estate. Our inspectors document these external defects with precision so you can require the developer to address them before you move in.
Stonewood Homes are known for higher specifications than volume housebuilders - EPC A-rated predicted ratings, EV chargers, and higher-quality joinery than a typical Persimmon or Taylor Wimpey plot. But a higher specification sets a higher bar. Our inspectors know what good looks like at this price point and will hold the standard.
Tell us your property address, size, and target inspection date. Our system generates a fixed price quote immediately - no hidden fees, no call back required.
We recommend booking your snagging inspection as close to legal completion as possible - after the developer's final clean but before you move your belongings in. Our inspectors cover BS25 and surrounding North Somerset with flexible dates.
Our inspector arrives at your Winscombe, Sandford, or Churchill property and conducts a methodical room-by-room inspection covering all accessible areas. You can attend if you wish or leave the inspector to work independently.
Your written snagging report is delivered within 24 hours of the inspection. Every defect is photographed, described, and referenced to the NHBC Buildmark warranty standards so your developer cannot dispute the findings.
We help you submit the snagging list formally to your developer. Under NHBC warranty terms, the developer is obliged to rectify genuine defects within two years of legal completion. Most developers address snagging lists within 8-12 weeks.
BS25 property has risen 13% in value year-on-year to December 2025. At £497,093 average and with Meadow Gate plots ranging from £395,000 to £659,950, buyers in this postcode are committing substantial sums. A snagging survey typically costs between £295 and £495 - that's less than 0.1% of purchase price for a property at the lower end of the BS25 market.
Defects caught during snagging are free to remedy under your NHBC Buildmark warranty. Once the two-year snagging period expires, any repair costs become yours. Our inspectors have helped BS25 buyers recover thousands of pounds of remediation work from developers across Somerset - drainage rectification, re-pointing, window seal replacements and plastering repairs all add up quickly if not caught in time.

Our snagging surveys in BS25 start from £295 for a 2-3 bed new build. For 4-bed properties like The Grittleton or The Norton at Stonewood Homes' Meadow Gate development in Sandford, prices start from £395. The exact cost depends on your property's square footage and the number of rooms to inspect. You'll get a fixed price quote instantly online with no obligation to proceed.
Book as soon as your developer confirms a legal completion date, but schedule the inspection after the developer's final clean and before you move your furniture in. For Meadow Gate buyers, Stonewood Homes will give you a predicted completion date during the reservation process - we recommend booking with us at the same time so you have your slot secured. The optimal window is the 1-3 days between keys being released and your removal van arriving.
A typical 3-4 bed new build in BS25 takes 3-5 hours to inspect thoroughly. Our inspector works systematically through every room, including loft space, garage, and external areas including garden boundaries and drainage outlets. For larger 5-bed detached properties common in BS25, allow 5-6 hours. You'll receive your full written report within 24 hours of the inspection completing.
Yes - in BS25 we specifically verify that drainage specification and groundworks are appropriate for Carboniferous Limestone karst terrain. The Mendip Hills are named by the BGS as a primary sinkhole risk area, meaning drainage from new builds needs to be correctly routed and unobstructed. We also check for the presence and correct installation of a radon barrier membrane - the Mendip Hills are a PHE-designated Radon Affected Area and new builds should have this protection built in.
Yes, we cover all of BS25 including Winscombe, Sandford, Shipham, Churchill, Compton Bishop and Rowberrow. New builds across the postcode qualify for our fixed-price snagging survey. Note that Shipham sits on historically mined ground from 18th-century calamine (zinc ore) extraction - we include ground-level checks relevant to this in our Shipham inspections, including any visible settlement or cracking at floor or wall junctions.
Your NHBC Buildmark warranty (standard on Stonewood Homes and most volume housebuilder properties) gives you a two-year defect liability period. During this period, the developer is contractually obliged to address genuine defects. If your developer is unresponsive, you can escalate to the NHBC Resolution service. Our snagging reports are formatted to meet NHBC evidential standards - photographs, descriptions, and location references - which strengthens any escalation case significantly.
BS25's elevated limestone villages - Winscombe, Sandford, Shipham, Churchill - carry low river and coastal flood risk compared to the Somerset Levels flatlands in BS26 and BS27. The Environment Agency has no active flood alert zones covering the main BS25 settlements. However, karst groundwater can rise after heavy rainfall events, and valley-bottom plots in Winscombe may have localised surface water risk. We check that drainage outlets and perimeter drains are clear and correctly graded, which is the main practical protection for any new build.
Our inspectors find an average of 40-60 documented snags across a typical new build, and BS25 properties are no exception. Common findings in North Somerset new builds include silicon bead failures around sanitary fittings, gaps at skirting board junctions, external brickwork pointing voids, gutter alignment issues on pitched roofs, and door and window seal inconsistencies. Higher-specification developments like Stonewood Homes' Meadow Gate carry higher buyer expectations, so we apply thorough scrutiny to joinery quality, finish levels, and EV charger installation that comes standard with these plots.
