Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
After the work
To get the most from the new sealant:
- Share drawings and the specification as soon as possible
- Don’t schedule sealing before decorators and flooring are done
- Brief the final clean team to avoid blades near sealant
- Don’t force external sealing on a damp or frosty day
Once an area is sealed, protect it from following trades. Fresh sealant needs its cure time before it’s cleaned, painted near or knocked.
Snag items left to the last week put handover at risk. Clearing snags area by area spreads the work out.
Construction mastic in Upper Swanmore
A typical mastic package covers more than window perimeters: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. One contractor for all of it keeps the responsibility in one place, and one applicator team gives a consistent finish. If you have mastic snags holding up handover and frame perimeters left unsealed or poorly sealed, we can put it right, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Upper Swanmore is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Construction in and around smaller places such as Upper Swanmore is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Advice
Construction mastic around Upper Swanmore: points for this area
Upper Swanmore is in the South East, one of the UK’s drier regions. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack. Upper Swanmore is about 60 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme.
New units and refits on sites such as Swanmore Business Park, 1.1 miles to the south-west of Upper Swanmore, need their panel and perimeter joints sealed to the specification. For contractors at a school such as Swanmore Church of England Aided Primary School, sealing has to be finished before term starts.

Common problems we fix in Upper Swanmore
Shrinkage and settlement in the first months put new joints under strain. Plaster, screeds, timber and blockwork all shrink as they lose moisture and internal caulk in a moving joint is normally the first to crack. Picking a flexible sealant where there’s movement keeps snags down.
Look out for the following:
- Inconsistent sealant finishes from plot to plot
- External joints sealed in damp or cold conditions that are now failing
- Caulk cracking where joints are moving more than expected
- Bath and shower joints scraped during the final clean
Hospital estates such as Knowle Hospital (5.1 miles south of Upper Swanmore) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.
Before you book anyone
- How they handle RAMS and site documents
- Who will actually carry out the work
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- What the guarantee covers, and for how long
When to bring in a specialist
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
Common questions from Upper Swanmore clients
Can you take on a job at a hospital such as Knowle Hospital?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
Is Upper Swanmore too small for you to travel to?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Can you work to our specification?
Specification first, then the maker’s instructions. Preparation, backing and depth follow the product guidance.
Will you quote for a small job?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
When can you be on site?
We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
Is the mastic package guaranteed?
Each package is backed by a 12-month guarantee. We carry five million pounds of public liability insurance.
Are you fully insured?
Yes. We’re fully insured, including public liability cover.
Cost factors for mastic packages
Each job is priced on its own details. The things that drive the figure:
- The site’s rules and procedures
- How much existing material needs removing
- Quantities, in metres or numbers
- Distance, for remote addresses
We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote.
Before you send an enquiry
It doesn’t need to be a full survey. A few details are enough to get going:
- The postcode of the building
- Any dates the work must fit around
- Whether an asbestos survey exists
- Whether the building will be occupied during the work
For a fixed quote, phone 01277 525 020 or send details through our quote form, telling us the site location and the nature of the job. Our quote form is another easy route.
What we can’t put right
Honesty saves time and money. Fresh joints won’t solve:
- Specifying the product where the designer hasn’t
- Frame gaps too wide for sealant, which the installer needs to correct
- Approving fire stopping as compliant
Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we’ll tell you honestly before you book.
