Keeping the joints sound
Regular inspection catches problems early. In particular:
- Avoid piecemeal callouts where you can
- Prioritise elevations facing the weather
- Encourage occupiers to report problems at frames
- Include mastic in your cyclical inspections
If paintable sealant was used, decoration can follow once it has cured. Non-paintable silicone shouldn’t be painted over unless told otherwise.
The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing and the job grows.
How we handle mastic sealing in Hatherden
We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. A planned, building-by-building programme often works better than reacting to each complaint and we quote and schedule each building in turn. Site teams most often ask us about no planned programme for sealant and brittle perimeter mastic across a building, across external wall and movement joints, balcony and threshold joints and window and door perimeters on blocks. Facilities teams, main contractors and managing agents in Hatherden tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
In and around smaller places like Hatherden, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Should maintenance staff do it?
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.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Your questions answered
Is Hatherden too small for you to travel to?
No. Places such as Hatherden are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Can you quote for a block close to Andover station?
Yes, we work for agents, landlords and housing associations with blocks of every size. We work to your notice and access arrangements.
How long do sealant joints last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Can you plan resealing across several buildings?
We can. We survey and price each building, then work through them in order, and the programme can start with the worst.
How many days will you need on site?
The duration is planned around your programme and the access we are given. We will give you an estimate of time on site when we quote.
Do you guarantee the mastic work?
There is a 12-month guarantee on our workmanship and we hold public liability insurance.
Does weather matter for sealant work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Cost factors for mastic joints
Before we quote, we look at:
- Distance, for remote addresses
- Specialist products, such as fire-rated or hygienic sealants
- How accessible the joints are
- Whether the work must be split into stages
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
Sending details for a quote
There’s no need for a formal survey. A few details are enough to get going:
- Where the site is, with the postcode
- Clear photographs of the problem areas
- Whether an asbestos survey exists
- Any dates the work must fit around
Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

What the job involves on each surface
Tenement and older buildings
Older buildings, including Scotland’s sandstone tenements, have their own joint details. The material either side of the joint shapes the product choice.
Window and door perimeters on blocks
Window and door perimeters are where most mastic failure shows. We remove the failed mastic, prepare the faces, add backing rod if the joint is deep and reseal.
Planned mastic for Hatherden portfolios
Hatherden is about 63 miles from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres. Hatherden is in the South East, one of the UK’s drier regions. External mastic still waits for dry faces and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.
Churches, halls and community buildings such as Christchurch are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. For owners of several units at places like Portway Industrial Estate, 2.6 miles to the south of Hatherden, one programme can deal with frame and external mastic across the lot.

Advice
When to call us in Hatherden
Frames, panels and masonry expand and contract through the year, and every joint has to stretch and squeeze with them. If the joint or the product wasn’t suited to the movement, it splits and fails early.
Things that typically lead to an enquiry:
- A mix of products and colours from past repairs
- Complaints coming in block by block
- Draughts at frames across a block
- Communal area joints that look neglected
Schools and community buildings such as Hatherden Church of England Primary School need frame and external mastic kept sound like any building.
Questions to ask before you book
- How they’ll work around occupants
- Their approach to joint depth and backing
- Proof of insurance
- Whether primer will be used where the manufacturer specifies it
