Work for main contractors and building owners
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
Construction mastic in Wymering, done properly
External mastic depends on the weather in a way most internal trades don’t. Cold or damp mornings, frost and condensation on frames can all hold external sealing up, so we plan elevations with the forecast and the programme in mind. Internal sealing often fills those days. We work on cladding and panel joints, brick and block movement joints and window and door perimeters, and the usual reasons a site gets in touch are different trades sealing to different standards and frame gaps too wide for sealant alone. For commercial sealant work in Wymering, you deal with one contact from quote to sign-off, whether it’s one building or several.
In a smaller place such as Wymering, construction tends to mean small housing schemes, conversions and extensions to community buildings. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Advice
Quoting for work in Wymering
Quotes vary with the job. It mainly depends on:
- The site’s rules and procedures
- How much there is to seal
- Which sealant the job calls for
- Whether the work must be split into stages
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.
Details that help us quote
A few photographs plus some basic facts will normally do. Please tell us:
- Whether an asbestos survey exists
- The type of building and who uses it
- Rough lengths or quantities, or drawings if you have them
- A wide shot and a close-up of the area
A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or phone 01277 525 020 or use the quote form to discuss it first.

Construction mastic around Wymering: what changes locally
With the shore within about 1 mile, Wymering counts as a coastal location. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so we check the specified product suits the exposure before the first bead. Wymering is about 62 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes.
On a healthcare site such as Queen Alexandra Hospital, which lies north-east of Wymering, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. For a contractor at a hotel such as Village Hotel, under half a mile south of Wymering, the mastic often has to be finished before a reopening date. Recladding or extending a unit at a site like Oak Park Industrial Estate, under half a mile west of Wymering, brings panel joints and frame perimeters into the programme.
Wymering is about 3 miles north of Portsmouth, in Portsmouth. We cover Wymering and the rest of Portsmouth, with the same fixed quotes and 12-month guarantee as everywhere else. We work across 19 places in Portsmouth, large and small.

Your questions answered
Does a coastal location like Wymering affect which sealant is used?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Is Wymering off your patch?
No. Places such as Wymering are covered as much as the big towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Will you come and look before quoting?
That depends on the size and complexity of the job. Simple work can often be priced from photographs, and bigger or more complex jobs typically get a visit.
Can you work to our specification?
Specification first, then the maker’s instructions. Primers, backing and joint depth follow what the manufacturer sets out.
Can the sealant be colour-matched?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and the quote will be based on it.
What will the job cost?
There isn’t a price list, because every site is different. Send photos or drawings and we will price it at a fixed figure.
Why it’s worth doing now in Wymering
Clearing snags piecemeal is tempting when handover is close. A planned sweep of each plot or floor catches the lot in one go, and avoids repeated visits. We can run snagging as its own phase before handover. For buildings in places like Wymering, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.

Should maintenance staff do it?
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
Surface by surface
External facade and movement joints
Brickwork, blockwork and panel movement joints need a sealant with the right movement capability. Depth is controlled with backing rod so the bead bonds to two sides only.
Window and door perimeters
Internal perimeters are typically sealed with a paintable product where decorating follows. The specification decides which, and colour-matched products can be used where the frame is on show.
