Independent new build inspections across BN18 - Arundel, Yapton, Walberton and the Arun villages








BN18 is one of the most active new build markets in West Sussex right now. Barratt's Ryebank Gate in Yapton, Esquire's Arundel Gate, David Wilson Homes' Sylvan Meadows in Walberton, and Crayfern's Five Acres are all completing or selling off-plan in 2024-2025. Each development sits on ground that brings specific challenges: the River Arun flood plain runs through the district, South Downs chalk underlies the eastern villages, and the Sussex clay weald covers the western rural fringe. Our inspectors understand what to look for on each site type.
A snagging survey places a qualified inspector on your side before your developer hands over the keys. We check every room, external wall, roof, drainage run, and service installation - producing a photographic defect report you hand directly to the site manager. Builders are obliged to rectify genuine defects before completion. Without this inspection, you accept the property as built.

Arundel sits on the River Arun and has a designated Flood Warning Area covering Warningcamp, Burpham, and properties along River Road and Arun Street. The Environment Agency's Arundel Tidal Defence Scheme was accelerated specifically due to flood and erosion risk to existing properties, and the River Arun has reached a peak recorded level of 3.65m. New builds in BN18 - particularly those on the Yapton and Walberton clay plain west of the castle - should be checked for ground floor slab levels relative to the 1-in-100-year flood plain, drainage design, and any anti-flood measures specified in the planning permission. Our snagging inspectors flag where flood mitigation details specified in planning conditions have not been fully implemented, which is a defect the developer must correct before you complete.
BN18 has an unusually wide spread of new build activity for a semi-rural West Sussex district. The schemes range from Esquire Developments' 90-home Arundel Gate (Ford Road, BN18 9EX) - winner of best Residential Development in West Sussex - through to smaller rural infill schemes in Walberton and Yapton.
Each of these developments has a different builder, different contract specification, and different ground conditions. Our BN18 inspectors are familiar with all of them.

Arundel town is one of the most architecturally distinctive places in West Sussex. The castle - seat of the Dukes of Norfolk since the Norman Conquest - sits above a town of knapped flint terraces, stone-dressed cottages, and Victorian Gothic revival public buildings. British History Online records flint and beach pebble construction with brick dressings throughout the historic core, and 18th-century brick and flint houses line Arun Street, Park Place, and Mount Pleasant.
New build activity has moved largely away from the historic core - planning conservation controls make development within the town's medieval street pattern near-impossible - and concentrates instead in the satellite villages of Yapton, Walberton, and Ford. These are traditional West Sussex agricultural settlements now absorbing volume and boutique house builders on their rural fringes. The soil here is Sussex Weald clay: a shrink-swell clay that moves significantly between wet and dry seasons. Ground floor slab cracking, threshold gaps, and door frame distortion in the first 12-18 months of a new build on clay are not unusual, and a snagging survey catches these before the builder's obligation expires.
The result is a BN18 market where buyers might be purchasing a Georgian flint cottage in Arundel, a David Wilson Homes semi in Walberton, or a Barratt apartment in Yapton - each with a completely different defect risk profile. For new build buyers specifically, a professional snagging inspection is the most direct way to protect that investment.
Prices are fixed and inclusive. No travel surcharge for BN18 postcodes. Quote confirmed before booking.
Enter your Arundel or Yapton postcode, number of bedrooms, and expected legal completion date. You'll receive a fixed price in under a minute. No call required, no site visit charge.
We cover all BN18 developments - Arundel Gate, Ryebank Gate, Avisford Grange, Five Acres, Sylvan Meadows, and smaller schemes. We recommend booking 1-2 weeks before your completion date to allow time for defect rectification before you move in.
We spend 2-3 hours on a typical three-bedroom new build. We use moisture meters, spirit levels, and visual inspection protocols based on NHBC Buildmark warranty standards and the developer's own building specification.
Every defect is photographed, located on a room-by-room basis, and cross-referenced to the relevant NHBC or building regulations standard. BN18 reports typically identify 30-90 items. The format is designed for direct submission to the site manager.
Your developer is legally obliged to respond to every item under their NHBC warranty. We advise you on responses received and support any formal NHBC Resolution Service referrals if the developer is unresponsive.
New builds in Yapton, Walberton, and Ford sit on Sussex Weald clay - a shrink-swell clay that expands in wet winters and contracts in dry summers. Builders typically use deeper foundations on clay ground, but the superstructure still moves slightly as the clay cycles. Our inspectors record cracking patterns in plaster and render that indicate early settlement, checking whether patterns are consistent with normal thermal movement or suggest something more significant.
To the north and east of BN18, toward Amberley and the South Downs, the underlying geology changes to chalk - which drains freely but dissolves slowly and can develop voids. Properties on chalk tend to suffer less from settlement but more from drainage problems and damp ingress at ground level. Our inspection protocol adapts to the likely ground conditions for each specific site.

Snagging surveys in BN18 start from £295 for a one-bedroom property. A three-bedroom home - the most common size at Ryebank Gate and Five Acres - typically costs from £395. Four and five-bedroom homes at Arundel Gate are priced from £449. All quotes are fixed-price with no travel surcharge for BN18 postcodes, and are confirmed before you book.
We cover all active BN18 developments: Arundel Gate (Esquire, Ford Road), Ryebank Gate (Barratt, Yapton), Avisford Grange (Vistry/Linden Homes, Walberton), Five Acres (Crayfern, Yapton), Sylvan Meadows (David Wilson Homes, Walberton), The Steddles (Yapton), and smaller infill schemes across the district. If your development isn't listed, contact us - we cover the whole BN18 postcode area.
Yes, for some BN18 sites it is directly relevant. The River Arun has a designated Flood Warning Area covering Arundel, Warningcamp, and Burpham. Developments on or near the flood plain should have specific anti-flood measures built into their planning conditions - raised floor levels, tanked basements, flood-resistant door thresholds, or drainage attenuation systems. Our inspectors check whether these measures have been built as specified. If a developer has not implemented a condition attached to their planning permission, that is a defect you can require them to rectify before completion.
A standard three-bedroom house takes 2-3 hours. Larger properties at Arundel Gate (4-5 bedroom homes) may take 3-4 hours. We don't rush the inspection - if we find a complex defect that requires further investigation, we take the time. Your report is issued within 48 hours of the inspection.
Yes, and we recommend it. The best window is 1-2 weeks before your completion date, giving the developer time to rectify defects before you take ownership. Access before completion is at the developer's discretion - some will allow it, others prefer to complete first. If access is refused pre-completion, book for the first working day after you receive your keys. The NHBC warranty applies from legal completion, and the two-year defects period begins on that date regardless of when the survey takes place.
Sussex Weald clay is a shrink-swell clay that changes volume significantly between wet and dry seasons. On new builds in Yapton and Walberton, the most common clay-related findings in the first year are: internal plaster cracking at wall-ceiling junctions and above door frames, gaps appearing between skirting boards and floor, and minor movement in door frames causing latches to bind. These can indicate normal thermal movement or early differential settlement. Our inspector assesses the crack pattern and records whether it requires developer action or simply monitoring, giving you a documented baseline for any future claim.
Yes. We inspect all major volume housebuilders operating in BN18, including Barratt Homes (Ryebank Gate, Yapton) and David Wilson Homes (Sylvan Meadows, Walberton). These are both Barratt Developments Group brands, which means they share many site processes and subcontractors. Our inspectors know the common defect patterns on Barratt and David Wilson Homes developments - including the specific ceiling heights and plaster finishes used on their standard house types - and focus their checks accordingly.
Arundel Gate is covered by NHBC Buildmark warranty, which gives you two years of defects coverage from legal completion and ten years of structural coverage. If Esquire Developments refuses to action items from our report, our next step is to help you submit a formal NHBC Resolution Service claim - backed by our photographic evidence and technical report. NHBC as the warranty provider has leverage over the developer that individual purchasers often don't have. We support you through this process at no additional charge.
