Homebuyer Drain Survey in Solihull

A homebuyer drain survey is one of the most cost-effective checks you can commission before purchasing a property. A standard structural survey will not inspect underground drainage — the surveyor will note visible access chambers and may flag drainage as a concern, but will not send a camera into the pipes. Only a dedicated CCTV drain survey tells you exactly what is happening inside the drains you are about to own.

In Solihull, this matters particularly because the borough contains several housing eras and materials that carry well-known drainage risks. Understanding what is beneath a property before you buy protects you from inheriting problems that are expensive to repair and impossible to claim against the vendor once contracts have exchanged.

Drainage Risks by Area in Solihull

Chelmsley Wood and Smiths Wood (B37). These estates were developed rapidly in the 1960s and early 1970s using pitch fibre drainage as standard. As of 2026, the majority of original pitch fibre in these areas is between 55 and 70 years old. Deformation is common — the pipes narrow from a circular cross-section to an oval or hour-glass shape that restricts flow and is prone to sudden collapse. A pre-purchase CCTV survey will show the current condition of the pipes and whether relining is needed. This is especially important because pitch fibre problems are invisible from the surface until a blockage or collapse occurs.

Shirley and Olton (B90, B92). These established suburbs have significant stocks of 1930s to 1950s semi-detached and detached houses. Original clay drainage beneath large, garden-heavy plots is common, and decades of root ingress from mature trees is a routine finding. Our homebuyer surveys in Shirley and Olton regularly identify root infiltration that the homeowner has been unaware of — either because the drain still flows freely between inspections or because it has only caused a problem once before.

Knowle and Dorridge (B93). Executive and period properties in this area often have larger, more complex drainage layouts — including surface water systems serving driveways and outbuildings — and may sit on ground subject to seasonal movement on Keuper Marl. Many larger properties in this area have had extensions or alterations made over the years, creating unofficial drain connections or abandoned pipe sections that the current owner may be unaware of. A CCTV survey maps the drainage network and confirms everything is connected correctly.

What the Report Contains

Our homebuyer drain survey report contains everything a property buyer, solicitor, or surveyor needs to assess the drainage condition. Each defect is logged with its WRc condition grade (the industry-standard scoring system), its distance from the access point, and a description. The report includes stills from the CCTV footage and a written summary in plain English. Where we identify defects that are Severn Trent Water's responsibility rather than the property owner's, we note this clearly — this can be significant in properties close to the public sewer boundary.

Using the Report in Your Purchase

A drain survey report can be used in three ways. First, if the drains are in good condition, it gives you confidence to proceed without reservation. Second, if minor defects are found, you have documented evidence to use in price negotiations or to request a retention. Third, if significant defects are found — a collapsed section, widespread pitch fibre deformation, or major root ingress — you can make an informed decision about whether to proceed, renegotiate, or walk away before you are legally committed.
