About our mastic sealing in Branstone
Most buildings come with mastic joints nobody has looked at since handover and it slowly wears out: window perimeters, door frames, external joints and communal junctions all rely on it. When it hardens, splits or pulls away, water and draughts follow, and occupiers start reporting it. We work on shopfronts below residential blocks, balcony and threshold joints and external wall and movement joints, and what we are called in for most is repeated reactive repairs to the same buildings and a mix of products and colours from past repairs. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Branstone, preparation and product choice get the time they need.
Owners and agents with buildings around smaller places such as Branstone tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.
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.

Frames, entrances and external joints in Branstone
Branstone sits close to the coast, within about 3 miles. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first, so it’s worth inspecting those sides more often. Branstone sits in one of the drier corners of the country, the South East. Outside mastic still needs a dry joint and the right temperature, and the sunniest, most exposed sides of a building usually need attention first.
Churches, halls and community buildings such as All Saints' Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Landlords with units on estates such as Branstone Business Park, under half a mile to the south of Branstone, can bring frame, door and external mastic across several units into one programme. For a school such as Newchurch Primary School, perimeter mastic on windows and doors is a holiday job.

What else we do in Branstone
Leave it or put it right?
Resealing ahead of leaks keeps it to a maintenance task. Once water has tracked in, the repair list grows and occupiers notice. One visit to deal with every failing joint makes more sense than several trips to a place like Branstone. Send photos of each area and we’ll quote for the lot.
The price depends on the quantity of joints, what has to come out first and the access. Call for a fixed quote when you’re ready.

Common questions from Branstone clients
Do you work for managing agents with blocks near Shanklin station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Send the address, photographs of the elevations and your access arrangements, and we’ll give a fixed quote.
Is Branstone Business Park, near Branstone, within your area?
Yes. We cover Branstone and the area around it, including industrial estates, business parks and retail parks such as Branstone Business Park. Photos and a short description are enough for a first look.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Can you reseal a whole block or estate?
Block-wide and estate programmes are common. You get a fixed quote per building or for the whole job.
Which sealant will you use?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
What about access for upper-floor joints?
We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned, and we will tell you how we’d approach it.
Will residents or tenants be disturbed?
Residents and tenants carry on as normal. If any flats or units need access, we will tell you in advance so it can be arranged.
What sets the cost
To price the job, we consider:
- Any access equipment needed
- Which sealant the job calls for
- Whether old sealant has to be cut out first
- The total length or number of joints
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.
Before you send an enquiry
A good diagnosis starts with the right details. Tell us:
- Whether the building will be occupied during the work
- Any dates the work must fit around
- How the joints are reached, and at what height
- Drawings or a marked-up plan, if available
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, phone 01277 525 020 or send details through our quote form.
Looking after the joints
Regular inspection catches problems early. Specifically:
- Start inspections with the most exposed faces
- Keep bins and bikes away from communal door frames
- Check the asbestos register before any old mastic is disturbed
- Plan resealing building by building rather than complaint by complaint
Include sealant in planned building inspections. Check for splits, open joints, brittle mastic and lifting edges and record where they are.
Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings and work down the list.
