Mastic sealing near Highfield
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
After the work
Cleaning and maintenance staff play a part too. Pass these on to them:
- Look at the sunniest and most exposed elevations first
- Mention RAMS, insurance or CSCS requirements up front
- Plan resealing building by building rather than complaint by complaint
- Keep bins and bikes away from communal door frames
If a joint we sealed fails within 12 months, tell us and we will look at it. Beyond that, routine checks spot the next round of repairs.
Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and the complaints that come with it.
Mastic sealing in Highfield, done properly
We diagnose before we prescribe: which joints have failed, why, and whether sealant is the right answer. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in, with backing rod setting the depth where it’s needed. We work on shopfronts below residential blocks, communal entrances and stairwells and balcony and threshold joints, and what we’re called in for most is a mix of products and colours from past repairs and no planned programme for sealant. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Highfield is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Older buildings and conversions around places like Highfield mix old masonry with newer frames. The mastic there needs to suit both surfaces.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What happens if it’s left?
Failed perimeter mastic lets cold air in around frames, and they often blame the windows. Resealing the perimeters is often the simpler fix where the frames themselves are sound. Small buildings around Highfield suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Frames, entrances and external joints in Highfield
With the shore within about 3 miles, Highfield counts as a coastal location. On buildings near the shore, the side facing the weather usually needs its mastic renewed first, so it’s worth inspecting those sides more often. The 2 miles around Highfield include two care or nursing homes. Owners of care premises can bring window and door mastic into a phased programme planned around the home.
Site managers at schools like Highfield Church of England Primary School can fit frame mastic into the summer works. Churches, halls and community buildings such as Highfield Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

Do you need mastic sealing in Highfield?
We often find joints filled solid with no backing rod so the mastic is bonded on three sides. That three-sided adhesion stops it stretching and it tears.
Clients normally get in touch after noticing something like this:
- Open joints in brickwork or panels
- Occupiers reporting cold air round windows
- Estate-wide sealant that is simply worn out
- Damaged joints in communal entrances and corridors
Student blocks close to universities like University of Southampton, less than half a mile to the south of Highfield, are easiest to work on between tenancies.

Advice
Common questions from Highfield clients
Can being near the sea in Highfield affect the sealant we need?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Is Highfield too far out for you?
Not at all. Highfield is within our area. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.
What if the old mastic contains asbestos?
Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Can you plan resealing across several buildings?
Block-wide and estate programmes are common. The quote can be split however suits your budgeting.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
What will the job cost?
We don’t publish prices, because every site is different. Send photographs or drawings and we will price it at a fixed figure.
