Mastic sealing in Broadbridge
Blocks are lived in, so access and disruption have to be thought through. Dates, areas and the order of work are agreed with you in advance, giving you what you need to notify residents. Communal entrances and stairs stay usable while we work. Site teams most often ask us about the same joint failures repeated across a portfolio and worn sealant at communal door frames, across shopfronts below residential blocks, balcony and threshold joints and communal entrances and stairwells. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Broadbridge is the same: the right product in a properly prepared joint.
Around smaller places like Broadbridge, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.
Our 12-month guarantee is about workmanship, not 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.

Planned mastic for Broadbridge portfolios
Broadbridge is within about 3 miles of the coast. 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. Broadbridge has five care or nursing homes no more than 2 miles away. For owners and operators of care buildings, window perimeters and external joints are best renewed in planned phases around residents.
Landlords with units on estates such as Broadbridge Business Centre (less than half a mile west of Broadbridge) can bring frame, door and external mastic across several units into one programme. If you look after a block within reach of Bosham station, less than half a mile north of Broadbridge, frame and balcony mastic can be renewed on one programme.

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Rural sites near Broadbridge may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- First comes a look at the joints and, for older buildings, the asbestos records.

- Failed mastic is removed completely.
- Joint faces are cleaned, backed and resealed.
- We finish each building before moving to the next.

Related advice
Should maintenance staff do it?
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Nearby places to Broadbridge
What else we do in Broadbridge
FAQs: Broadbridge
Can being near the sea in Broadbridge affect the sealant we need?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Is Broadbridge off your patch?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
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.
Does weather matter for sealant work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Do you check for asbestos in old sealant?
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.
Which sealant will you use?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
How long will the new sealant last?
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.
Honest limits
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:
- 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
- Leaks through the frame itself rather than the perimeter
If in doubt, phone 01277 525 020 or email us and we’ll say what we think.
Joints and surfaces we work on
- Balcony and threshold joints
- Window and door perimeters on blocks
- External wall and movement joints
- Shopfronts below residential blocks
- Communal kitchens and washrooms
- Communal entrances and stairwells
Aftercare for building managers
Once the work is signed off, a little attention goes a long way:
- Share your contractor requirements early
- Group repairs into a planned programme
- Reduce knocks to communal area joints
- Track which buildings were done and when
Where a paintable product was specified, it can be painted after curing. Silicone usually can’t be painted, so keep decorators off it.
Leaks at window perimeters spoil finishes and can affect frames. Resealing early keeps the job small.
When to call us in Broadbridge
Frames, panels and masonry expand and contract through the year, and the sealant takes up that movement. A joint that was too narrow, too thin or the wrong product can’t cope long before it should.
Common reasons buildings call us in:
- Estate-wide sealant that is simply worn out
- A mix of products and colours from past repairs
- Failed external movement joints
- Window mastic that has split and shrunk
Churches, halls and community buildings such as The United Reformed Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.
