Construction mastic for Tower Hamlets sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Owners, agents and contractors
We work for building owners and managing agents on everything from one building to a spread of sites around Tower Hamlets. One quote can cover more than one site, which keeps the paperwork simple.

Construction mastic in Tower Hamlets, done properly
Refurbishment work needs a slightly different approach from new build. Old beads come out completely, as fresh silicone can’t grip old and the asbestos survey is checked first on older stock. New and existing joints then get the same preparation. The enquiries we see most involve sealant knocked or painted over by other trades and existing joints on a refurb that need cutting out and resealing, on brick and block movement joints, window and door perimeters and sanitary and kitchen joints. Whoever orders the work in Tower Hamlets, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Around places like Tower Hamlets, a lot of construction is the conversion of older buildings, and the sealant at those junctions has to cope with two materials that move differently, in a colour the planners or architect are happy with.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Cost factors for mastic packages
These are the things that shape the price:
- Removal of failed or old sealant
- The size and state of each joint
- Site requirements such as inductions and permits
- The product specified
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.
Sending details for a quote
A few photographs plus some basic facts will normally do. Please tell us:
- Clear photos of the problem areas
- The asbestos register, for older buildings
- The product your specification calls for
- Anything awkward about access or site hours
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
Surface by surface
Fire-rated sealant where specified
Not every penetration suits a sealant. Other products are used for some services and gaps. Tell us what records you need and we will confirm with the quote.
Bathrooms, en suites and washrooms
In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Joints are cleaned, sealed and tooled neatly and baths are loaded where appropriate before sealing.
Your questions answered
Does your area include sites such as White Cliffs Business Park, near Tower Hamlets?
Yes. Estates, retail parks and business parks around Tower Hamlets, White Cliffs Business Park among them, are all within reach. Photos and a short description are enough for a first look.
Our building in Tower Hamlets is near the coast: does that change the sealant?
It can. Coastal exposure works external joints harder than inland weather. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
What hours do you work?
We are in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.
Can fire-rated sealing at service penetrations be included?
It can be part of the package where specified. Tell us what records you need and we will confirm with the quote.
Can you work to our specification?
Yes. Send it with your enquiry, and we will price the work to it, flagging anything that needs clarifying.
Can you work to our specification?
We use the product the specification names. Any suggested alternative is put to you before anything changes.
Can you quote from photographs?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
Diagnose, treat, sign off
When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work usually takes whatever the programme allows, since the work follows the trades as areas are released. Work in places the size of Tower Hamlets is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- First we take quantities off the drawings and read through the specification.
- A fixed quote sets out the scope, the products and the sequence.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- We seal each plot or floor as it’s released to us.
- Each joint is prepared, backed to depth and sealed in the product the specification names.
- Snags are cleared before handover and completed areas carry our 12-month guarantee.
Before we start on site
- Send your site hours and access windows
- Point out parking and an unloading spot
- Point out any areas we must not close

Keeping the joints sound
Problems stay small when the joints are checked regularly. In particular:
- Brief following trades on areas that have been sealed
- Get the mastic subcontractor involved early in the programme
- Don’t force external sealing on a damp or frosty day
- Keep product details for future maintenance
Record which products went where in the handover file. That helps the building owner maintain the joints later. Tell us what records you need and we will confirm with the quote.
Snag items left to the last week put handover at risk. A planned close-out through each area as it completes keeps the list short and keeps handover on track.
New build and refits around Tower Hamlets
The sea is no more than about 1 mile from Tower Hamlets. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, so joint design, primers and product choice deserve extra care. Tower Hamlets sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so the external programme keeps a little slack.
Units on estates such as White Cliffs Business Park (1.6 miles north of Tower Hamlets) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. For a contractor at a hotel such as The Priory Hotel (under half a mile south-east of Tower Hamlets), the mastic often has to be finished before a reopening date.

Do you need construction mastic in Tower Hamlets?
Frames installed with uneven gaps make perimeter sealing harder. Every product has limits on how wide a joint it can bridge, so gaps outside that range need sorting by the installer first. Better to raise it at the start than seal a joint that’s bound to fail.
Things that usually lead to an enquiry:
- Old sealant on a refurbishment that needs stripping before new work
- Bath and shower joints scraped during the final clean
- Different trades sealing to different standards
- Window and door perimeters that won’t pass inspection
Projects at schools like Priory Fields School work to term dates, so mastic is programmed tightly.
What your quote should include
- Proof of insurance
- Who will actually carry out the work
- Do they follow the manufacturer’s priming guidance?
- How joint depth will be controlled
