Mastic sealing for Tower Hill sites
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Signs you need mastic sealing in Tower Hill
Frames, panels and masonry expand and contract through the year, and the sealant takes up that movement. If the joint or the product wasn’t suited to the movement, it splits long before it should.
Typical triggers for a call:
- The same joint failures repeated across a portfolio
- Old repairs sealed over failed mastic
- Damaged joints in communal entrances and corridors
- Movement joints with sealant missing
Owners of student blocks near Northeastern University London (under half a mile south-east of Tower Hill) can schedule frame and external mastic for the summer vacation.
What to look for in a quote
- How they’ll work around occupants
- Whether old or failed sealant will be cut out, not overlaid
- Health and safety accreditation such as CHAS
- Whether primer will be used where the manufacturer specifies it
Mastic sealing in Tower Hill, done properly
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, with each block quoted and scheduled in turn. If you’re dealing with brittle perimeter mastic across a building and old repairs sealed over failed mastic, we can put it right. Whoever orders the work in Tower Hill, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
London has a large stock of purpose-built blocks, mansion flats and converted buildings managed by agents and housing associations. Mastic around windows, doors and balconies tends to fail across a whole block at a similar time.
Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What we can’t put right
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Water coming in from the roof or rainwater goods
- Broken glass or failed sealed units
- Frames that are rotten, warped or broken
If in doubt, ring 01277 525 020 or send photos by email and we’ll say what we think before you book.
What we seal
- Communal entrances and stairwells
- Balcony and threshold joints
- External wall and movement joints
- Shopfronts below residential blocks
- Window and door perimeters on blocks
- Communal kitchens and washrooms
For managing agents and facilities managers
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Tower Hill can form part of a wider programme.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
How the job changes by surface
External movement joints
Movement joints are cleaned out, backed with rod and resealed with a sealant of the right movement class.
Planned maintenance
Planned resealing replaces emergency callouts and spreads the work.
From enquiry to sign-off
We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- First we look at the mastic on each building and note what needs replacing.
- A fixed quote follows, split by block or building if that suits you.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- We remove the old mastic completely and clean the joint faces back.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Getting the site ready
- Arrange parking or a loading space
- For older buildings, check the asbestos register before work
- Let us know about inductions and permits

Your questions answered
Do you take on jobs in Tower Hill where loading and access are tightly controlled?
Yes, we plan every London job around the building’s own access rules. Share the building’s contractor rules and we will work to them.
Do you work for managing agents with blocks near London Fenchurch Street station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Photos of each elevation help us quote accurately.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
What about access for upper-floor joints?
It depends on the building. We agree access with you at quote stage so there are no surprises.
How many days will you need on site?
It depends on the scope, though a typical visit typically takes one or more days per building, depending on the joint lengths and the access. For bigger or phased jobs, we will set out a timescale with the quote.
Do you guarantee the mastic work?
There is a 12-month guarantee on our workmanship and we hold public liability insurance.
Do you cover Tower Hill?
Yes. Tower Hill falls within our area, and you can ring 01277 525 020 or send details through our quote form to get started.
Why deal with it now?
Dealing with failed joints one report at a time is slow and scattered. A planned programme treats each building once, under a single quote and a single programme. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Why us?
- Failed material removed, not covered up
- One number for every site we cover
- Products installed to the manufacturer’s instructions
- 12-month guarantee on workmanship
