Mastic sealing in St Mary Hoo, done properly
Blocks are lived in, so access and disruption have to be thought through. The sequence, the areas and the dates are settled with you, giving you what you need to notify residents. Communal entrances and stairs stay usable while we work. Most enquiries involve worn sealant at communal door frames and old repairs sealed over failed mastic, across shopfronts below residential blocks, external wall and movement joints and communal kitchens and washrooms. Facilities teams, main contractors and managing agents in St Mary Hoo tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Owners and agents with buildings around smaller places such as St Mary Hoo 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.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What sealant work can’t fix
We check first that sealant really is the fix. It won’t put right:
- Leaks through the frame itself rather than the perimeter
- Materials that need asbestos testing before work
- Substrate edges that need repairing first
Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we will tell you honestly before you book.
What we seal

Why act early in St Mary Hoo
Leaving failed external joints lets water reach the structure behind. Damp patches, stained plaster and decorating claims can follow, which is harder to deal with than resealing. Halls, stores and units around places like St Mary Hoo may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
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 will put a fixed figure on it.
Why appoint us

Advice
Mastic sealing in St Mary Hoo: the local picture
St Mary Hoo is within about 2 miles of the coast. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do, so it’s worth inspecting those sides more often. St Mary Hoo is in the South East, one of the UK’s drier regions. External mastic still waits for dry faces and the right temperature, while the elevations that take the most sun tend to show hardened mastic first.
Student blocks close to universities like University of Greenwich - Medway, 4.9 miles to the south-west of St Mary Hoo, are easiest to work on between tenancies.
St Mary Hoo is about 4 miles south of Canvey Island, in Medway. Commercial clients in St Mary Hoo can call on us for mastic joints, as part of our coverage of Medway.

Aftercare for building managers
Cleaning and maintenance staff play a part too. Share these points with them:
- Mention RAMS, insurance or CSCS requirements up front
- Group repairs into a planned programme
- Check the asbestos register before any old mastic is disturbed
- Encourage occupiers to report problems at frames
Add mastic joints to your cyclical inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away, and note the building and elevation.
Left open, joint edges in render, brick or frames can deteriorate. Once that happens, repairs come before resealing.

St Mary Hoo: questions and answers
Is St Mary Hoo off your patch?
No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Does a coastal location like St Mary Hoo affect which sealant is used?
It can. Coastal exposure works external joints harder than inland weather. We check the specified product suits the exposure and pay close attention to preparation.
Can you quote from photographs?
That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.
Do you guarantee the mastic work?
A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Is any job too small?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
What we’re called out for in St Mary Hoo
Buildings move with temperature and moisture, and every joint has to stretch and squeeze with them. A joint that was too narrow, too thin or the wrong product can’t cope and fails early.
Most enquiries start with one or more of the following:
- Mastic failing across several blocks on an estate
- Brittle perimeter mastic across a building
- Damaged joints in communal entrances and corridors
- Water getting in round frames after rain
Churches, halls and community buildings such as Church of St Mary are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.
What your quote should include
- How joint depth will be controlled
- Which product they’ll use, and why it suits the joint
- What site paperwork they can supply
- How the existing material will be dealt with
