Contractors’ notes for Cobham
Rainfall across the South East, Cobham included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, which is why external dates are agreed with the site manager. Cobham lies roughly 17 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme.
For contractors refurbishing units at places like Hersham Place Technology Park, 2.4 miles north of Cobham, the mastic covers cladding panels, roller-door and window perimeters. Historic houses such as The Homewood, 1.2 miles north of Cobham, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

How we handle construction mastic in Cobham
The programme rarely stands still, so the mastic package has to flex with it. We agree a sequence at the start and adjust it as the site manager releases areas and we don’t seal before other trades have finished in an area. That keeps the work right first time and saves rework. If you are dealing with frame perimeters left unsealed or poorly sealed and a mastic package split between trades with no clear owner, we can help, on cladding and panel joints, window and door perimeters and floor and skirting junctions alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Cobham it comes down to the same thing: the right product in a properly prepared joint.
Building work in places the size of Cobham is usually small-scale: a handful of new houses, barn conversions, a school or hall extension. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.
Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Quoting for work in Cobham
These are the things that shape the price:
- Travel to remote or island sites
- Working within restricted access windows
- The product specified
- The site’s rules and procedures
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
Details that help us quote
It doesn’t need to be a full survey. These details are enough to start:
- What the building is and how it’s used
- Access details, including height
- The postcode of the building
- When you need the work done
A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or phone 01277 525 020 or send photos by email if you’d rather talk the job through.
Cobham: questions and answers
Is a hospital such as Cobham Community Hospital and Health Centre somewhere you can work?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Is Cobham too far out for you?
Not at all. Cobham is within our area. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.
Do you take on small jobs?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
Are you insured?
Yes. We are fully insured, and the certificate can go with your quote.
Do you take on mastic snagging only?
Yes. We clear snags by redoing joints rather than patching them.
What site paperwork can you supply?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
Do you do fire-rated sealing on new builds?
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested details. The design and sign-off belong to the designer, fire engineer or building control.
When to call us in Cobham
Frames installed with uneven gaps make perimeter sealing harder. Sealant has a range of joint widths it can cope with. Better to raise it at the start than seal a joint that’s bound to fail.
Site and facilities staff are often the first to spot these:
- Sanitary sealant damaged by following trades
- Frame gaps too wide for sealant alone
- Window and door perimeters that won’t pass inspection
- Inconsistent sealant finishes from plot to plot
When a school such as St Andrew's CofE Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.

Why deal with it now?
Leaving mastic to whichever trade is fitting the element can look cheaper on paper. In practice it often means different standards, gaps in responsibility and snags nobody owns. A single mastic package gives one point of responsibility, with the same standard on every plot. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.
We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.

Doing it in-house
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Keeping the joints sound
Regular inspection catches problems early. Specifically:
- Note which sealant went where at handover
- Ask installers to correct oversized gaps first
- Stick to the specified sealant rather than a generic substitute
- Ask cleaners to use soft cloths around fresh sealant
Brief the sparkle clean so they don’t scrape the new joints. Blades and abrasive pads are the commonest cause of damage at the final clean so keep them off the joints.
Oversized gaps are a problem better caught early. Sealant stretched over an oversized gap won’t last, so the installer needs to correct it first. We flag them as soon as we see them.
