Mastic sealing for commercial buildings in Boarhunt
Owners and agents usually inherit a building’s mastic rather than choose it, and it ages quietly: it sits round windows and doors, along external joints and through communal areas. When it hardens, splits or pulls away, water and draughts follow, and occupiers start reporting it. We work on balcony and threshold joints, communal entrances and stairwells and shopfronts below residential blocks, and the failures we’re asked to look at most are mastic failing across several blocks on an estate and no planned programme for sealant. Whether you call it commercial sealant work, mastic application or joint sealing, in Boarhunt it comes down to the same thing: the right product in a properly prepared joint.
For owners with a single building near Boarhunt, we plan to finish in one visit where possible. Send photographs of the frames and joints and we will give a fixed quote.
Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off.

Advice

Frames, entrances and external joints in Boarhunt
Boarhunt sits close to the coast, within about 2 miles. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first. Boarhunt is about 63 miles from central London. Managed blocks of flats are a big part of commuter-belt property; their frame mastic often ages block-wide.
If you’re responsible for a building such as Church of St Nicholas, frame and door mastic needs the same attention as any other property. Blocks of flats and mixed-use buildings often cluster around stations such as Portchester station (to the south-east of Boarhunt) and their window and balcony mastic tends to age at the same rate across a building. If your remit includes a building such as Cams Hill School, frame and door mastic can be programmed for the holidays.
Boarhunt is about 3 miles north-east of Fareham, in Hampshire. Any commercial site in Boarhunt is covered, whether it’s a single job or part of a planned programme. Boarhunt is one of 723 places we cover in Hampshire for mastic joints.

What affects the price in Boarhunt
These are the things that shape the price:
- The site’s rules and procedures
- Whether old sealant has to be cut out first
- The product specified
- The size and state of each joint
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.
Before you send an enquiry
To price the job accurately, we need to understand the site. Send us:
- Drawings or a marked-up plan, if available
- Whether the building will be occupied during the work
- Photos of the joints, close up and from further back
- Whether an asbestos survey exists
Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.
When it isn’t the sealant
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Frames that are rotten, warped or broken
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Roof leaks, gutters or failed flashings that aren’t sealant joints
Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.
What we seal
- Communal entrances and stairwells
- External wall and movement joints
- Communal kitchens and washrooms
- Shopfronts below residential blocks
- Balcony and threshold joints
- Window and door perimeters on blocks
Maintenance after handover
For the best life from the joints:
- Make it easy for occupiers to report draughts
- Group repairs into a planned programme
- List the paperwork your organisation requires when you send details
- Have the asbestos survey to hand for older buildings
Log the date and extent of the resealing for each block. That makes future programmes easier to plan and shows what was done.
Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings so spending is spread.
Different surfaces, different methods
Estate-wide resealing programmes
Using the same products throughout keeps the estate consistent and easier to manage.
Planned maintenance
Adding mastic to planned maintenance avoids reactive repairs and keeps budgets predictable.
Your questions answered
Is Boarhunt too small for you to travel to?
Not at all. Boarhunt is within our area. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.
Our building in Boarhunt is near the coast: does that change the sealant?
It can. Coastal exposure works external joints harder than inland weather. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Can you work to our specification?
Yes. Send it with your enquiry, and we will price the work to it, flagging anything that needs clarifying.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
How do we ask for a quote?
There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.
What if the old mastic contains asbestos?
We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on in line with the dutyholder’s asbestos management.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
