Working in St Neots
Working in our own town
St Neots is home ground for Prime Build Services. The yard sits on St Mary's Street just off the town centre, which means Jack and Martin already know the housing stock street by street: the Victorian and Edwardian terraces around Priory Road and the town centre conservation area, the 1930s semis further out towards Eynesbury, the big post-war estates around Eaton Socon and Little Paxton, and the newer estates that have gone up over the last fifteen years towards Loves Farm, Wintringham and Cambourne Road. Each of those brings a different job. The old terraces near the river often need lime pointing done properly rather than cement slapped on, because cement traps moisture in soft old brick and causes more damage than it fixes. The 1930s semis are a common source of load-bearing wall removals and steel beam jobs when people open up the kitchen. The newer estates tend to bring garden work, patios, driveways and fencing, because the gardens are handed over as a flat lawn and nothing else.
Ground conditions around St Neots vary within a few streets. Close to the River Great Ouse and the flood plain that runs through the middle of town, the ground is often soft, clay-heavy and prone to holding water, which matters for foundations, patios and driveways alike, get the drainage and sub-base wrong here and a new patio will be lifting within a couple of winters. Further out towards Eynesbury and the gravel terraces the ground drains better and behaves differently again. None of this needs guessing when you already know the town; it's why the first visit is always to look at the actual ground and the actual house rather than price from a photo.
St Neots is also where recent stonework has been carried out to a high standard: a 60 square metre natural stone slip installation with lime pointing was completed for a customer, Nick Watt, with the kind of attention to detail that lime work demands; it has to be mixed and applied correctly or it fails. That job is a fair example of the standard applied to every re-pointing and stone slip job taken on locally, whether it's a full elevation or a single chimney breast.

Why use a St Neots builder based in St Neots
There's a practical advantage to using a builder whose yard is in the town you live in. Site visits, deliveries and follow-up snags don't involve a long drive, and Jack already has a working sense of what planning and conservation constraints tend to apply in different parts of town before he's even walked round the back. That doesn't replace looking at the actual job, every quote still starts with a proper visit, but it does mean fewer surprises.
Martin has been in the trade for longer than Jack and taught him the work; the two of them now work jobs together, which matters on anything involving older brick or lime mortar where getting it wrong is expensive to undo. The business carries £2 million insurance and every job comes with a 6-month workmanship guarantee, and the phone is answered 24 hours a day, seven days a week.

Local building conditions
Common problems seen in St Neots homes
A few issues come up repeatedly across the town's different housing types.
Cement pointing on old brick
Terraces and older buildings near the town centre were often pointed with cement mortar at some point, which traps moisture in soft old brick and leads to spalling. Lime pointing lets the wall breathe and matches how it was originally built.
Water sitting near the Ouse flood plain
Patios, driveways and garden levels close to the river need proper falls and drainage built in from the start, or water sits and undermines the surface over a wet Cambridgeshire winter.
Bare gardens on new-build plots
New-build estates around Wintringham and Loves Farm are often handed over with a lawn and nothing else, no proper patio, paths or boundary treatment, leaving a garden that needs designing from scratch.
Load-bearing walls in 1930s semis
Opening up a kitchen or knocking through a lounge in the town's 1930s stock usually means a load-bearing wall, so a steel beam has to be sized and installed correctly.
Tired boundary walls and fencing
Older boundary walls and fence lines across Eaton Socon and Little Paxton often need rebuilding rather than patching once they've moved or leaned.

Common questions
Building in St Neots:
straight answers
Do you cover all of St Neots, including Eynesbury and Eaton Socon?
Yes. The yard is on St Mary's Street in the town centre, and jobs are carried out right across St Neots including Eynesbury, Eaton Socon, Little Paxton and the newer estates.
How quickly can you come and look at a job in St Neots?
The phone is answered 24 hours a day, 7 days a week, and because the business is based in St Neots itself, Jack will arrange a time to come and look at the job around what else is booked in.
How much will my job cost?
There's no set price without seeing the job. Jack visits, looks at what's involved and prices it properly rather than guessing over the phone.
Can you work outside normal hours?
The phone is answered around the clock, so get in touch whenever suits and Jack will talk through timing for a visit.
Is the work guaranteed?
Yes, every job carries a 6-month workmanship guarantee, and the business holds £2 million insurance.
How long does a typical extension or renovation take?
Timescales vary depending on the job: an extension takes longer than a re-pointing job or a patio. Jack will give a realistic timeframe once he's seen the work involved.
Do I need planning permission for my project?
That depends on the property and the scope of work. Jack will tell you during the visit if something is likely to need planning or building control approval, and any building work is carried out to approved drawings where they're required.
Do you match brick and stone on older St Neots properties?
Yes, matching materials to the existing building is standard practice, particularly on the older terraces and Victorian properties near the town centre where brick colour and mortar type matter.
Can you take on a full house renovation as well as smaller jobs?
Yes, from full renovations and extensions down to a single wall or a driveway. The same visit-and-price process applies whatever the size of the job.
Do you do lime pointing on period properties?
Yes, lime pointing is regularly carried out on older St Neots brick, including a recent 60 sq m natural stone slip and lime pointing job completed for a St Neots customer.
