About our construction mastic in Ham
We work to the specification and the programme, not to habit. Where the specification names a product, we use it, and if an alternative is proposed, it goes to you for acceptance first. Joint widths, backing, primers and tooling follow the manufacturer’s guidance, so the joints perform as the designer intended. Site teams most often ask us about mastic snags holding up handover and sealant knocked or painted over by other trades, on internal decorators’ caulk, window and door perimeters and floor and skirting junctions. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Ham it comes down to the same thing: the right product in a properly prepared joint.
A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by, so tidy, well-planned work matters.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Leave it or put it right?
Patching snags as they appear can feel quicker than a proper close-out. A planned sweep of each plot or floor catches the lot in one go. We can run snagging as its own phase before handover. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote when you’re ready.

Aftercare for building managers
Once the work is signed off, a little attention goes a long way:
- Share drawings and the specification as soon as possible
- Ask cleaners to use soft cloths around fresh sealant
- Release areas for mastic once other trades have finished in them
- Flag uneven or tapered frame gaps early
The package carries our 12-month guarantee for workmanship. The guarantee covers how we sealed, not later damage by other trades.
Sanitary joints that fail early become defects soon after occupation. Water gets behind trays, vanity tops and panels, leaving the remedial work to the contractor. Getting the product and preparation right first time avoids that.
Do you need construction mastic in Ham?
A new building moves while it dries and settles. Materials lose construction moisture and shrink, which opens up internal joints, particularly where caulk has been used in a joint that moves. Picking a flexible sealant where there’s movement keeps snags down.
Common reasons buildings call us in:
- Window and door perimeters that won’t pass inspection
- A long mastic snag list close to completion
- New external sealant already peeling away
- Old sealant on a refurbishment that needs stripping before new work
Recladding or extending a unit at a site like St. George's Industrial Estate (to the south-east of Ham) brings panel joints and frame perimeters into the programme.
Before you book anyone
- Will failed sealant be removed rather than covered?
- Their pre-qualification and accreditations
- Can the work be phased to keep areas open?
- Will CSCS-carded applicators be on site?
Construction mastic in Ham: the local picture
Site traffic in Ham falls within London’s ULEZ, like everywhere else in Greater London. Add booked deliveries and tight storage, and the mastic package needs planning with the site team. Ham has a good number of hotels close by, all within 2 miles. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
University estates such as St Mary's University, 1 mile west of Ham, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. Work at a hotel such as Alexander Pope Hotel (to the west of Ham) tends to be programmed around bookings, mastic included.

- Whether an asbestos survey exists
- Clear photographs of the problem areas
- Whether the building will be occupied during the work
- The product your specification calls for
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, give us a call on 01277 525 020 or email us.
General trades versus a specialist
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
From enquiry to sign-off
On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself typically taking a day or two on a small fit-out and several weeks on a large multi-storey package. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. 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.
- The sequence is agreed with the site manager.
- Each area is sealed when it’s released.
- Joints are prepared, backed and sealed to the specification.
- After snagging, the work is handed over under our 12-month guarantee.
Getting the site ready
- Point out any areas we must not close
- Let us know about inductions and permits
- Send your site hours and access windows
