Our process
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- Site photos, drawings or a visit tell us what’s there and how it has failed.
- A fixed quote follows, with removal and preparation included.
- We agree the order of work, access windows and site hours with you.
- The failed sealant comes out and the faces are prepared, with primer where required.
- Backing goes in, the new sealant is laid and tooled, and the area is left neat.
- Completed areas are signed off with you under our 12-month guarantee.
Before we start on site
- Agree which areas must stay open
- Send your site hours and access windows
- Make sure the joints can be reached

Havering-atte-Bower: questions and answers
Do you work in London buildings with loading restrictions?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Say when the building is occupied and when it’s quiet, and we will plan accordingly. All of Greater London is inside the ULEZ, and our planning allows for it
Is Havering-atte-Bower in the area you cover?
Yes, Havering-atte-Bower is within the area we cover. Our area covers London and the South East counties. To get started, just give us a call on 01277 525 020 or send photos by email with the address and what needs doing.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
What site paperwork can you provide?
We’ll confirm the paperwork you need, such as RAMS, an insurance certificate or CSCS details, with the quote. We hold CHAS accreditation and Constructionline membership and carry five million pounds of public liability insurance.
Is the old sealant taken out first?
Every scrap of failed sealant is removed before the new bead goes on. Sealing over traps water and lifts once the joint moves.
Do you take on multi-site sealant work?
Yes, we can. Give us the sites and the scope at each, and fixed prices follow, with a suggested sequence.
Is your work guaranteed?
Our workmanship on each job is backed by a 12-month guarantee. We are fully insured for public liability as well.
Do you need commercial sealant contractors in Havering-atte-Bower?
No sealant joint is permanent. How long one lasts depends on the movement it takes, its exposure to sun and weather, the cleaning regime, the traffic and the product itself. In commercial buildings those factors tend to act together, which is why regular inspection pays.
Site and facilities staff are often the first to spot these:
- External beads that have gone brittle and cracked
- Black mould through washroom sealant that won’t clean off
- Leaks that seem to come through a sealant line
- Frame mastic that has hardened and come away from the wall
Shops and cafés around stations like Harold Wood station, 2.7 miles to the south-east of Havering-atte-Bower, trade from early, so work is timed around them.
What to look for in a quote
- Will RAMS and insurance details be available?
- The terms of the workmanship guarantee
- How joint depth will be controlled
- Whether their applicators hold CSCS cards
What sets the cost
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- The product specified
- How accessible the joints are
- How much there is to seal
- How much existing material needs removing
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.
Before you send an enquiry
Whether it’s one area or a whole building, these details speed things up:
- What the building is and how it’s used
- Approximate linear metres or a joint schedule
- Where the site is, with the postcode
- The asbestos register, for older buildings
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.
What happens if it’s left?
Some low prices are low because nothing gets cut out. New sealant laid on old silicone has nothing to bond to, so it peels. Our prices always include removal of the failed bead and full joint preparation. Getting scaffold, permits or access booked in Havering-atte-Bower takes effort, so it makes sense to deal with every failing joint while access is in place.
Pricing sealant joints depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.
Why appoint us
- Fully insured
- Constructionline member
- One number for every site we cover
- Joints cleaned back to sound surfaces

Sealant on show in Havering-atte-Bower’s commercial buildings

For managing agents and facilities managers
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Havering-atte-Bower can form part of a wider programme across Greater London.
Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Havering-atte-Bower. Several sites can go on one quote, so there’s one set of paperwork to deal with.
After the work
Regular inspection catches problems early. Specifically:
- Keep a record of which joints were resealed and when
- Don’t let cleaning or traffic back on before the cure time is up
- Put external and wet-area joints on a regular inspection round
- Act on the first lifting edges rather than waiting
Add the resealed joints to your planned maintenance inspections. A periodic look catches splits and lifting edges early. Should something look amiss, you can call the office on 01277 525 020 or use the quote form and send a picture.
In kitchens and washrooms, a failed joint is a cleaning problem as well as a leak risk. Environmental health officers look at how cleanable surfaces are, which makes sound joints worth keeping on top of.
