Mastic sealing in Purbrook
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Doing it in-house
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
How we handle mastic sealing in Purbrook
There isn’t one mastic for every joint on a building. Window perimeters and external joints often take a low-modulus neutral-cure silicone, and MS polymer sealants stick well to many substrates and often take paint. We’ll confirm the colours available for the specified product. The enquiries we see most involve water getting in round frames after rain and open joints in brickwork or panels, on shopfronts below residential blocks, communal kitchens and washrooms and balcony and threshold joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Purbrook it comes down to the same thing: the right product in a properly prepared joint.
Towns the size of Purbrook have a mix of blocks, flats over shops and small commercial buildings looked after by agents and landlords. Window and door perimeters, external joints and communal areas all need their mastic renewed from time to time.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

How a job runs
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself normally taking anything from a day to a few weeks, depending on the number of buildings and joints. In a town such as Purbrook, most jobs are single buildings. We start with your photos, drawings or a site visit, then send a fixed quote.
- First we look at the mastic on each building and note what needs replacing.
- You get a fixed quote, priced per building where that helps your budgeting.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
What we need from you
- Move anything stored against the joints
- Warn occupants and staff about the work
- Have the specification and drawings to hand

For owners and agents in Purbrook
Purbrook sits close to the coast, within about 2 miles. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints; plan inspections around that. Central London is about 60 miles from Purbrook. Within reach of London, blocks run by agents and associations are common around stations; their frame mastic often ages block-wide.
Buildings close to stations like Bedhampton station (1.9 miles south-east of Purbrook) are often flats over shops, with frame mastic to keep sound. Churches, halls and community buildings such as Church of St John are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Site managers at schools like Purbrook Junior School can fit frame mastic into the summer works.

What sealant work can’t fix

- Asbestos-containing sealant, which we don’t remove

Why it’s worth doing now in Purbrook
Resealing ahead of leaks keeps it to a maintenance task. After water has got in, there may be damp, damaged plaster or decoration to put right too and occupiers notice. In Purbrook, as anywhere, the simplest time to fix a failed joint is before it leaks. Once water gets in, there’s drying out and making good as well.
What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a quote when you are ready.
Why appoint us
- 12 months’ guarantee on every job
- Coloured sealants to suit the setting, where available

What else we do in Purbrook
FAQs: Purbrook
Can you quote for a block close to Bedhampton 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.
Our building in Purbrook is near the coast: does that change the sealant?
It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We check the specified product suits the exposure and pay close attention to preparation.
What guarantee do you give on resealing?
Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.
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’ll confirm the approach in the quote.
Do you work with property factors and landlords?
Yes, block and estate work is a core part of what we do. Buildings are scheduled in turn so you can plan around it.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and the quote will be based on it.
Does weather matter for sealant work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
