Commercial sealant contractors for commercial buildings in Avery Hill
Most of the buildings we seal stay open while we are there. Work is scheduled around the site hours and access windows you give us. It’s the same approach in offices, retail units, hotels, schools and healthcare buildings. We work on external facade joints, movement joints in walls and floors and floor and threshold joints, and the failures we are asked to look at most are shrunken sealant along kitchen worktops and splashbacks and frame sealant that has cracked, shrunk or pulled away. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Avery Hill, that means joint design, primers and backing rod as standard.
Occupied buildings in Avery Hill need the work phased: we agree the order with you and hand back each area with its cure time.
London’s commercial stock mixes period buildings turned into offices with modern glass and steel, so one job can involve stone, brick, powder-coated frames and laminate in a single visit. The right product goes on each, in a colour chosen to suit where the joint is seen.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Building owners, agents and FMs in Avery Hill
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
On site: what to expect
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself normally takes anything from part of a day on a short run of joints to several weeks on a large phased package, and our waste is bagged and taken away as we go. For a job in Avery Hill, access comes first. Give us the hours we can be on site and we’ll schedule to suit.
- Send details through our quote form, or ask for a site visit.
- The cause is diagnosed and the scope priced as a fixed quote.
- Work is phased around your occupiers where areas need to stay in use.
- Every failed bead is removed rather than covered.

Questions we’re asked in Avery Hill
Will you take on work at estates like Green Lane Business Park, close to Avery Hill?
Yes. Our area takes in Avery Hill and its surroundings, with estates and business parks such as Green Lane Business Park included. To start, just speak to us on 01277 525 020 or email us with the unit, the joints involved and your access times.
Does a hotel in Avery Hill need to shut while its sealant is renewed?
In most cases no closure is needed: we work room by room or floor by floor. The plan is built around your bookings.
Who decides which product is used?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Is it OK to apply fresh sealant over existing beads?
The old bead is stripped out first. After that come cleaning, primer where needed, backing and the new sealant.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it.

Yes. Sites across Avery Hill are covered, with one number for every area we cover.

What happens if it’s left?
Fixing joints complaint by complaint is a costly way to manage sealant. A planned programme groups work by building or area, cuts repeat visits and gives you a budget figure. We’ll suggest an order, worst sealant joints first. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Putting it right early is less disruptive than dealing with the consequences.
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.

Doing it in-house
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
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, which is what makes a joint last.
What we’re called out for in Avery Hill
If sealant tears through its centre, it has failed cohesively. That normally means the joint stretched further than the product could cope with. The same product in the same joint tends to fail the same way.
Clients usually get in touch after noticing something like this:
- Smeared sealant across finishes from a rushed job
- Mouldy silicone around WCs, urinals and vanity tops
- Leaks that seem to come through a sealant line
- Frame mastic that has hardened and come away from the wall
If you run an office at a site such as Green Lane Business Park (1.2 miles south-west of Avery Hill), the sealant at reception desks, tea points and frames ages with each fit-out.
Questions to ask before you book
- Which product they’ll use, and why it suits the joint
- Whether old or failed sealant will be cut out, not overlaid
- Whether their applicators hold CSCS cards
- Will RAMS and insurance details be available?
When it isn’t the sealant
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Removing asbestos-containing materials (a licensed or specialist contractor’s job)
- A failed roof covering or waterproofing membrane
- A dripping trap, valve or pipe behind a fitting
