Construction mastic for commercial buildings in Stoke Newington
Since 2005 we’ve worked alongside main contractors, developers and fit-out firms. We price from drawings and the specification, agree the sequence with the site team and seal as areas are released. For construction mastic on a scheme in Stoke Newington, send drawings through our quote form, or phone or email us to talk it through. Site teams most often ask us about oversized or tapered gaps around new frames and sealant knocked or painted over by other trades, on cladding and panel joints, sanitary and kitchen joints and window and door perimeters. Whoever orders the work in Stoke Newington, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Stoke Newington must meet its standards or pay the daily charge. Add booked delivery slots and limited storage, and a London mastic package needs planning before the first bead.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Surface by surface
Bathrooms, en suites and washrooms
On multi-unit schemes, consistency matters across hundreds of bathrooms. A single team keeps the standard consistent.
External facade and movement joints
External movement joints often need primer, depending on the substrate. Primer goes on where the sealant maker calls for it, and seal only with a dry joint inside the product’s temperature range.
Leave it or put it right?
On a refurbishment, there’s a choice between resealing existing frames and replacing them. Sound frames often need only a new perimeter seal and that’s a far smaller job. We will say so if a frame itself is the problem. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

When to call us in Stoke Newington
Frames installed with uneven gaps make perimeter sealing harder. Every product has limits on how wide a joint it can bridge and gaps beyond it need packing or adjusting by the frame installer. Better to raise it at the start than seal a joint that’s bound to fail.
What tends to prompt an enquiry:
- Perimeter gaps outside the sealant’s range
- Internal caulk splitting as the building dries out
- Old sealant on a refurbishment that needs stripping before new work
- A long mastic snag list close to completion
For a contractor at a hotel such as The Rose Hotel, which lies south-east of Stoke Newington, the mastic often has to be finished before a reopening date.
Comparing quotes
- Health and safety accreditation such as CHAS
- Will failed sealant be removed rather than covered?
- Whether their applicators hold CSCS cards
- Their approach to joint depth and backing
After the work
After handover, these steps help:
- Record the products used in the O&M file
- Stick to the specified sealant rather than a generic substitute
- Brief the final clean team to avoid blades near sealant
- Ask installers to correct oversized gaps first
The package carries our 12-month guarantee for workmanship. The guarantee covers how we sealed, not later damage by other trades which is why protection after sealing matters.
One unsealed frame can let water into finished internal areas. On a new building that means remedial work after decorating, and a delay to handover. A check of every frame before decorators start is worth the time.

London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for. Stoke Newington has a good number of hotels close by, all within 2 miles. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.

Recladding or extending a unit at a site like Frogmore Industrial Estate (0.9 miles south-west of Stoke Newington) brings panel joints and frame perimeters into the programme.

Our process
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. In Stoke Newington, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- We start with the drawings, specification and programme.
- We take off quantities and return a fixed quote.
- We agree with the site team which areas come first.
- Plots or floors are sealed as they’re handed over.
- Every joint is cleaned, set to depth and sealed with the specified product.
- After snagging, the work is handed over under our 12-month guarantee.
What we need from you
- Send any specification or drawings in advance
- Send your site hours and access windows
- Make sure the joints can be reached

Advice
What sealant work can’t fix
We check first that sealant really is the fix. It isn’t the answer for:
- Frame gaps too wide for sealant, which the installer needs to correct
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Defective windows, doors or glazing units (the supplier or installer’s job)
Not sure which it is? You can give us a call on 01277 525 020 or email drawings and photos and we will tell you honestly.
What we seal
- Internal decorators’ caulk
- Sanitary and kitchen joints
- Window and door perimeters
- Floor and skirting junctions
- Brick and block movement joints
- Cladding and panel joints
