North Wales new builds carry unique risks - coal mining subsidence, River Alyn flood compliance, and strict Welsh Building Regulations our inspectors know inside out.








CH7 covers Mold, Buckley, Mynydd Isa and dozens of Flintshire villages - an area where three distinct snagging risk factors come together. Our inspectors have found North Wales Coalfield subsidence damage in new builds sitting above old mine workings, documented SuDS drainage systems that fail to meet the mandatory Welsh requirements introduced in 2019, and spotted Welsh Part L 2022 energy compliance failures that housebuilders hoped would go unnoticed.
Active sites at Bryn Castell (Lovell Homes, New Brighton Road CH7 6ZA) and Hawthorn Meadows (Castle Green Homes, Well Street Buckley CH7 2PQ) are both delivering NHBC-registered homes - but NHBC registration is not a substitute for an independent inspection. Our inspectors work for you, not the developer, and report everything they find.
With 48.2% of CH7 housing stock in detached properties and average prices at £249,849, a snagging survey costing from £295 is a straightforward investment before the developer's responsibility window closes.

CH7 sits above the Flintshire Coalfield, the westernmost section of the North Wales Coalfield. The Mining Remediation Authority has recorded six confirmed subsidence incidents in Flintshire since May 2022 alone. Abandoned mine workings can cause ground movement decades after closure, and a standard NHBC warranty does not protect you if subsidence arises from pre-existing mine workings beneath your plot. Our snagging inspectors flag early warning signs - sticking doors, hairline cracks in mortar courses, uneven floor levels - and recommend a Coal Authority CON29M search where risk is identified. If you are buying in Buckley (CH7 2 or 3), Sychdyn, or the hillside villages west of Mold, treat a mining search as essential, not optional.

Wales diverged from England's building regulations in 2012, and the gap has widened since. New homes in CH7 completed from November 2022 must comply with Welsh Part L 2022 - a stricter energy standard than the equivalent English regulations. Our inspectors check that insulation installations match the approved drawings, that the SAP rating evidence is credible, and that EV charging points and air-source heat pump installations (where specified) are correctly commissioned.
SuDS (sustainable drainage systems) are mandatory for all new Welsh development since January 2019, approved by the SAB (SuDS Approving Body) at Flintshire County Council. Our inspections include a check of visible drainage infrastructure - permeable paving, attenuation tanks, and soakaway specifications - against the approved drainage plan.

Two major housebuilder schemes are currently active within CH7. Lovell Homes at Bryn Castell (New Brighton Road, CH7 6ZA) is delivering 2-5 bedroom homes priced from £264,995 for a 3-bedroom semi up to £509,995 for a 5-bedroom detached. Our inspectors cover the Lovell Homes product range and consistently flag cavity wall insulation voids, incomplete rendering at eaves junctions, and first-fix electrical items left incomplete at handover.
Castle Green Homes at Hawthorn Meadows (Well Street, Buckley CH7 2PQ) is delivering 76 homes across its 3 and 4-bedroom range, priced from £274,995. Castle Green is an award-winning regional developer - and even well-regarded builders produce snagging lists. Our inspectors check every home against the same 300-point checklist regardless of developer reputation.
Smaller exclusive developments also exist across the CH7 area, from the 10-plot Dol Uchaf scheme in Gwernymynydd to individual self-build plots on the Clwydian Range fringe. All are eligible for a snagging inspection before or shortly after handover.
Parc Broncoed on Broncoed Lane, Mold (CH7 1BN) is delivering 80 homes across 3 and 4-bedroom house types. Our inspectors cover this development as standard - contact us once you receive your build completion notice from the developer.
Prices from £295 are correct for standard CH7 new builds. Properties in remote rural locations may carry a small travel surcharge. Our inspectors quote for the full address before booking.
The River Alyn flows through Mold town centre and is subject to active flood warning coverage by Natural Resources Wales. NRW maintains a monitoring station at Leadmill Bridge and issues flood warnings covering Leadmill, Ponterwyl, Glanyrafon, Pentre and Broncoed - all within the CH7 1 sector. New developments near the river corridor must demonstrate compliance with NRW's Technical Advice Note 15 (Development and Flood Risk) before planning consent is granted.
Our inspectors check that new build properties in flood-sensitive locations have the flood-resilience features specified in the planning conditions - raised floor levels, appropriate door and vent threshold heights, and correctly installed flood-resistant materials. A developer handover does not guarantee that these items were built to the approved specification; our inspection does.
Loggerheads Country Park, 4 miles south-west of Mold, has experienced severe flooding in both 2023 and October 2024. New flood defence works are under construction in that area. Properties on the Denbighshire-Flintshire border near the River Alyn headwaters warrant particular attention to drainage and ground-level compliance.

Enter your CH7 postcode and property details for an immediate price. Most CH7 new builds are quoted within 60 seconds - no waiting for callbacks.
Our inspector travels to Mold, Buckley, Mynydd Isa, Northop and surrounding CH7 villages. Pick a date that works for your handover timeline - we can inspect before or after legal completion.
Our inspector spends 2-4 hours on-site depending on property size, working through a 300-point checklist. They focus on Welsh regulatory compliance, structural elements, and the finish quality specific to your developer.
Your snagging report is delivered within 24 hours. It includes photographs, defect descriptions, and a categorised list ready to send directly to your developer's aftercare team.
Once the developer confirms repairs are complete, we offer a follow-up inspection to check the work is done. Most of the significant items are resolved within the first few weeks if you report them promptly.
Our snagging surveys in CH7 start from £295 for a 2-3 bedroom new build. The price scales with property size - a 4-bedroom detached (the most common type in CH7, which is 48% detached) is typically £349, and a 5-bedroom home from £399. Properties in remote Clwydian Range villages may carry a small travel surcharge, but the vast majority of CH7 addresses - Mold, Buckley, Mynydd Isa, Sychdyn, Northop - are covered at standard rates. We quote for your full address before you book.
Yes - and it is particularly important for both active CH7 developers. Lovell Homes at Bryn Castell (CH7 6ZA) and Castle Green at Hawthorn Meadows (CH7 2PQ) are both NHBC-registered builders with reasonable reputations, but our inspectors find meaningful snag lists at every development regardless of brand. Common items at volume housebuilder sites include cavity wall insulation voids, incomplete silicone seals at wet rooms, misaligned kitchen doors, incomplete external render at junctions, and SuDS drainage items left in an unapproved state. The point of an independent inspection is that our inspector works for you - not for the developer - and has no incentive to minimise the list.
A typical 3-bedroom semi-detached in Mold or Buckley takes around 2-3 hours to inspect thoroughly. Larger 4 or 5-bedroom detached homes - common in CH7 given the high proportion of detached stock - take 3-4 hours. Our inspector works systematically through every room, loft space, garage, external fabric, and drainage-visible elements. You receive the written report within 24 hours of the inspection.
Yes, and it is one of the most important issues to understand before buying in certain CH7 postcodes. The Flintshire Coalfield underlies parts of CH7 2 and CH7 3 (Buckley and surrounds), and the Mining Remediation Authority has recorded six confirmed subsidence incidents in Flintshire since May 2022. Our snagging inspectors look for early warning signs - sticking doors and windows, hairline cracks in mortar courses, uneven floor levels - that could indicate ground movement. If we identify indicators of concern, we recommend commissioning a formal Coal Authority CON29M search as part of your conveyancing. NHBC warranty does not cover damage caused by pre-existing mine workings.
The ideal time is in the final week before your legal completion date. This gives you a current snag list to hand to the developer's site manager before money changes hands, and creates a document record that pre-dates your ownership. If you have already completed, you still have a right to report defects under the NHBC Buildmark warranty during the two-year developer period (years 1-2) and the structural warranty period beyond that. We recommend inspecting as soon as possible after completion if you did not inspect before - developers are most responsive in the period immediately after handover.
Our snagging inspections in CH7 include checks relevant to Welsh Building Regulations, which diverged from England in 2012 and have since introduced stricter energy and drainage requirements. We check visible evidence of Part L 2022 compliance (insulation quality, heating system installation, EV charging point commissioning where fitted), and we verify that SuDS drainage infrastructure appears to have been installed as approved by Flintshire County Council's SAB. We are not a Building Regulations compliance body, but our reports flag observable issues that merit further investigation and give you documented evidence for any conversations with the developer or Building Control.
Yes - our inspectors cover the full CH7 district including rural addresses in Loggerheads, Halkyn, Gwernymynydd, Treuddyn, Caerwys and Leeswood, as well as urban addresses in Mold, Buckley and Mynydd Isa. Properties near Halkyn Mountain benefit from an additional awareness of historic lead and zinc mine workings in that area - we look for signs of ground instability and recommend specialist investigation where indicated. A small travel surcharge applies to the most remote Clwydian Range addresses.
Nationally, the Home Builders Federation 2025 survey found 93.7% of new build buyers reported problems to their builder after moving in, with 26.2% reporting more than 15 defects. CH7 new builds are consistent with these figures. Our inspectors typically produce reports listing 40-80 items on a new three or four-bedroom home, spanning cosmetic issues (paint drips, scratched tiles, chipped skirting) through to substantive items (incomplete cavity insulation, drainage non-compliance, poorly sealed window frames). The cosmetic items are straightforward to resolve; it is the substantive items that justify the cost of inspection.
