How we handle mastic sealing in Somers Town
Treatment starts with a proper look: which joints have failed, why, and whether sealant is the right answer. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed and backing rod used wherever a joint is deep. We work on external wall and movement joints, communal kitchens and washrooms and balcony and threshold joints, and the usual reasons a site gets in touch are movement joints with sealant missing and complaints coming in block by block. Facilities teams, main contractors and managing agents in Somers Town tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Across Greater London, Somers Town included, the ULEZ applies, and parking and loading rules differ from street to street. For block-wide work, a place to park and store materials saves time on every visit.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

FAQs: Somers Town
Do you take on jobs in Somers Town where loading and access are tightly controlled?
Yes. Inductions, permits and timed loading are routine for us in London. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly.
Will you take on work at estates like Roman Way Industrial Estate, close to Somers Town?
Yes. Our area takes in Somers Town and its surroundings, with estates and business parks such as Roman Way Industrial Estate included. A few photographs and the unit address let us price the work.
Can weather delay the job?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
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.
Do you supply RAMS and insurance details?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We hold CHAS accreditation and Constructionline membership.
Can you plan resealing across several buildings?
Yes, planned programmes suit estates and portfolios. The quote can be split however suits your budgeting.
Will you come and look before quoting?
It depends on the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.
Doing it in-house
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Keeping the joints sound
Cleaning and maintenance staff play a part too. Pass these on to them:
- Protect low-level joints in entrances
- Make it easy for occupiers to report draughts
- Have the asbestos survey to hand for older buildings
- Make mastic part of routine maintenance checks
Add mastic joints to your cyclical inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away and record where they are.
Mastic fails gradually, then all at once in a wet spell. Acting at the first signs keeps it a straightforward reseal and the complaints that come with it.
On site: what to expect
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work typically takes a few days for most blocks, with larger programmes scheduled building by building. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- Each block or building is walked and the failed joints recorded with the likely cause.
- A fixed quote follows, split by block or building if that suits you.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Preparing the site
- Tell staff and tenants when we’ll be in
- Move anything stored against the joints
- Send any specification or drawings in advance

Related advice
Signs you need mastic sealing in Somers Town
Many failed joints were sealed without backing rod so the mastic is bonded on three sides. It can’t stretch properly and splits as the building moves.
Clients normally get in touch after noticing something like this:
- Water getting in round frames after rain
- Complaints coming in block by block
- Draughts at frames across a block
- Brittle perimeter mastic across a building
Churches, halls and community buildings such as St Mary's Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.
Questions to ask before you book
- Who will actually carry out the work
- Their approach to joint depth and backing
- Will failed sealant be removed rather than covered?
- Their plan for phasing and protecting the area
