Construction mastic in Slade Green
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Looking after the joints
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Ask installers to correct oversized gaps first
- Allow flexibility for external sealing in damp or cold weather
- Keep product details for future maintenance
- Protect sealed areas from following trades
Tell the builders’ clean team which areas have new sealant. Scrapers used on frames and worktops can nick or lift a new bead, so stick to soft cloths and gentle cleaners near sealant.
A missed perimeter seal on one window can wet the reveal and the plaster inside. On a new building that means remedial work after decorating and possibly a delayed handover. Checking perimeters before internal finishes go on avoids it.
Construction mastic in Slade Green, done properly
Refurbishment work needs a slightly different approach from new build. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone. New and existing joints then get the same preparation. Most enquiries involve old sealant on a refurbishment that needs stripping before new work and new external sealant already peeling away, across brick and block movement joints, window and door perimeters and internal decorators’ caulk. Whoever orders the work in Slade Green, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
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.
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.

Construction mastic around Slade Green: points for this area
Site traffic in Slade Green falls within London’s ULEZ, like everywhere else in Greater London. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for. A 2-mile radius around Slade Green takes in a number of hotels. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight.
Units on estates such as Manford Industrial Estate, 0.8 miles north of Slade Green, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. Building work at universities like University of Greenwich (to the south-east of Slade Green) is often timed for the summer, mastic included. On a healthcare site such as Erith and District Hospital, 1.5 miles north-west of Slade Green, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
Slade Green is about 1 mile south-east of Erith, in Greater London. We cover commercial sites throughout Slade Green, whether it’s a single job or part of a planned programme. Across Greater London, 764 places are covered, Slade Green among them. We also cover London, some 13 miles away.

Quoting for work in Slade Green
We price every job individually. The main factors are:
- How much there is to seal
- Any access equipment needed
- Induction, permit and paperwork requirements
- Whether old sealant has to be cut out first
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.
What to include in your enquiry
There’s no need for a formal survey. A few details are enough to get going:
- When you need the work done
- Rough lengths or quantities, or drawings if you have them
- What the building is and how it’s used
- The postcode of the building
A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or phone 01277 525 020 or email a schedule or drawings if you’d rather talk the job through.
How the job changes by surface
Snagging before handover
The last pass before handover is where mastic snags are cleared. We can work through the snag list area by area, cutting out damaged joints and resealing them properly.
Internal decorators’ caulk
Caulking is often done in a hurry by whoever’s on site. A neat, consistent caulk line makes the decorators’ job quicker and keeps the snag list down.
On site: what to expect
Tell us your site hours and access windows and we’ll plan around them. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. 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.
- First we look at the scope on site or from drawings.
- A fixed quote sets out scope, products and phasing.
- Paperwork is agreed and applicators are inducted on site.

Advice
Should maintenance staff do it?
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

FAQs: Slade Green
Can you work on a hospital site such as Erith and District Hospital?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Do you work in London buildings with loading restrictions?
Yes. Inductions, permits and timed loading are routine for us in London. Send the building rules and access times with your enquiry.
Do you have public liability insurance?
Yes. We’re fully insured, and the certificate can go with your quote.
What’s the quickest route to a quote?
You can use the quote form on this site; alternatively, call 01277 525 020 or send photos by email. Include photographs or drawings if you have them.
Does the weather affect the work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
How many days will you need on site?
We plan the time on site around your programme and access. You’ll have an expected duration with the quote.
What happens if old sealant might contain asbestos?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
