Mastic sealing across South Hornchurch
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Why act early in South Hornchurch
Open external joints let water into walls and around frames. Damp patches, stained plaster and decorating claims can follow and those cost far more to put right. Failed sealant in a building in South Hornchurch can quickly affect neighbours, tenants or the floor below: water travels through shared structures, and a small leak becomes a dispute between occupiers. Putting it right early is less disruptive than dealing with the consequences.
The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

How a job runs
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. In South Hornchurch, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- We check the asbestos register for older buildings and look at the joints.
- A fixed quote covers the joints, products and order of work.
- We strip out the old sealant.
- The joints are prepared and resealed with the right product.
- Buildings are completed in turn.
Getting the site ready

Questions about South Hornchurch
Can you work in a care home near South Hornchurch with residents in?
Yes. We agree rooms and times with the manager and work a few areas at a time. Noise and disruption are kept to a minimum.
Do you cover business parks and estates near South Hornchurch, such as Mudlands Industrial Park?
Yes, sites like Mudlands Industrial Park are within our area, along with the rest of South Hornchurch. Send details of the unit and the work through our quote form for a quick quote.
Do you work with property factors and landlords?
We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work and work can be quoted per building or as a whole.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Can weather delay the job?
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. Internal work is far less affected.
Do you guarantee the mastic work?
Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.
Maintenance after handover
For the best life from the joints:
- Keep a record of when each building was resealed
- Include mastic in your cyclical inspections
- Check the asbestos register before any old mastic is disturbed
- Ask residents or tenants to report leaks and draughts early
Protect entrance and corridor joints from knocks where possible. Knocks cause many early failures in communal areas.
Failed mastic often goes unnoticed until heavy rain finds it. Resealing when cracking first shows avoids water damage and saves internal repairs.

What we’re called out for in South Hornchurch
Communal entrances and corridors see a lot of wear, with joints near the floor and around doors suffering most. Regular cleaning wears them further.
Most enquiries start with something like this:
- Patchy repairs in mismatched sealant
- Draught complaints from residents or tenants
- Brittle perimeter mastic across a building
- No planned programme for sealant
Site managers at schools like Whybridge Junior School can fit frame mastic into the summer works.
Questions to ask before you book
- Is the sealant right for the movement and the substrate?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- How the existing material will be dealt with
- Their public liability cover
Should maintenance staff do it?
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Cost factors for mastic joints
We price every job individually. The main factors are:
- Location, for remote and island sites
- Whether old sealant has to be cut out first
- Quantities, in metres or numbers
- How accessible the joints are
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.
What to include in your enquiry
A good diagnosis starts with the right details. Tell us:
- Asbestos survey details if the building is older
- Your programme or deadline
- Drawings or a marked-up plan, if available
- Anything awkward about access or site hours
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, call 01277 525 020 or email us.
