What happens if it’s left?
Fixing joints complaint by complaint is a costly way to manage sealant. Planning the work across a year or a portfolio means fewer separate visits and a predictable spend. We can help you prioritise, starting with the joints most likely to let water in. In a London building, a failed joint rarely affects only one party. Putting it right early is less disruptive than dealing with the consequences.
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.
What you get with us
- Our applicators hold CSCS cards
- 12 months’ guarantee on every job
- Over 20 years of commercial sealing
- Fully insured

Commercial sealant contractors for commercial buildings in Brockley
Most commercial buildings carry hundreds of metres of sealant that nobody thinks about until it fails. We are commercial sealant applicators for FMs, managing agents, landlords and contractors with sites in Brockley. Our job is to diagnose the failure, remove the old bead and seal again using a product chosen for the movement and exposure. The enquiries we see most involve a top-up bead over failed sealant, now lifting and black mould through washroom sealant that won’t clean off, on kitchen worktops and splashbacks, window and door perimeters and movement joints in walls and floors. Looking for mastic applicators who cover Brockley? We’ve been sealing commercial buildings since 2005.
Occupied buildings in Brockley need the work phased: washrooms in turn, floors in sections and entrances kept open.
London’s commercial stock mixes period buildings turned into offices with modern glass and steel, which means one visit can cover joints against stone, brickwork, coated aluminium and shop-fit panels. Each surface gets its own preparation and, where it’s seen, a sealant colour that sits with it.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Frontages, fit-outs and joints in Brockley
Brockley has plenty of hotels close by, all within 2 miles. In hotels, sealant shows everywhere, from bathroom joints to reception counters, so colour and a clean finish matter, and the work can be phased so the rest of the hotel keeps trading. Less than 3 miles from Brockley there are at least three named estates and business parks. Tenant changes on such sites bring fit-outs, and fit-outs bring new joints; brand colours often come into it.
Offices and shops close to stations such as Crofton Park station, under half a mile to the north-west of Brockley, tend to be busy all day, so sealant work is planned around opening hours. On estates like Clyde Vale Industrial Estate, 1.5 miles south-west of Brockley, the office and welfare end of each unit has its own sealant to maintain.
Brockley is about 1 mile south of New Cross, in Greater London. Businesses, contractors and managing agents in Brockley use us for work on sealant joints. Our Greater London coverage takes in 764 places, large and small.
Commercial sites across SE4, SE23 and SE6 are covered for sealant joints. If your site is on Ivy Road, Nash Road and Lindal Road or close by, send details and we’ll quote for sealant joints. Sites close to Brockley are covered too, including Crofton Park (1 mile south-east), Honor Oak (1 mile west), Ladywell (1 mile east), Forest Hill (1 mile south-west) and Nunhead (1 mile north-west). A short drive away, we cover London (4 miles north-west), City of Westminster (7 miles north-west), Marylebone (7 miles north-west), Kensington (8 miles north-west), St Pancras (6 miles north-west) and Shoreditch (5 miles north).
Near you in Brockley
We work on buildings around Blythe Hill Tavern, Allenby Tutorial Trust and Blythe Hill Fields. Brockley has its own railway station: Crofton Park station. Well-known places in the area include Horniman Museum and Gardens (1.4 miles south-west) and University Hospital Lewisham (0.7 miles east). Green spaces nearby include One Tree Hill and Knight's Hill.
Doing it in-house
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Common questions from Brockley clients
Does your area include sites such as Clyde Vale Industrial Estate, near Brockley?
Yes, sites like Clyde Vale Industrial Estate are within our area, along with the rest of Brockley. Send details of the unit and the work through our quote form for a quick quote.
Can you work in a London building with booked loading and goods-lift slots?
Yes, most London buildings have access rules of some kind, and we plan around them. Send the building rules and access times with your enquiry.
How do we get a quote?
Price depends on joint lengths and widths, how much removal is involved, the product, access and phasing. To get a fixed price, send details through our quote form, or phone or email us.
How long does a job like this take?
The duration is planned around your programme and the access we’re given. We’ll give you an estimate of time on site when we quote.
Will your applicators have CSCS cards?
Yes. If you need card details for site access, tell us and we will confirm them with the quote.
Will the building have to shut during the work?
It’s normal for us to work in occupied buildings. Only the area being sealed is closed, and the sequence is agreed in advance, until its cure time has passed.
Can you work to our specification?
Yes. Send it with your enquiry, and we’ll price the work to it, flagging anything that needs clarifying.
When to call us in Brockley
Plenty of failed joints were never sealed with the right product. Painters’ acrylic in a moving joint, vinegar-smelling silicone on metal or natural stone, or a high-modulus product where a low-modulus one was needed all let go sooner than they should. BS 6213 gives guidance on choosing construction sealants, and many specifications refer to it.
Common reasons buildings call us in:
- Damp patches where an external joint has failed
- Shrunken sealant along kitchen worktops and splashbacks
- Expansion joints with the sealant torn out
- Sanitary sealant that has gone black and patchy
Sites a few miles apart, such as Clyde Vale Industrial Estate and Bell Green Retail Park, can share one programme and one point of contact.
What to look for in a quote
- What site paperwork they can supply
- Are they CHAS accredited or on Constructionline?
- How they’ll work around occupants
- Their approach to joint depth and backing
Our process
At the end of each section, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- First, details come to us: photographs, drawings or a schedule of the areas, and a site visit is booked where it helps.
- The failure is diagnosed and a fixed quote issued for the work agreed.
- Before anything is cut out, we agree access, timings and sequence.
- The failed bead is removed and the joint faces cleaned until they’re sound and dry.
- The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
- Each area is inspected, signed off and backed by our 12-month guarantee.
What we need from you
- Make sure the joints can be reached
- Confirm the product named in the specification
- Agree which areas must stay open

Cost factors for sealant joints
We price every job individually. The main factors are:
- Quantities, in metres or numbers
- Phasing around occupants
- Joint width, depth and condition
- Removal of failed or old sealant
What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a fixed quote once you have the details.
Sending details for a quote
We can often quote from photos and a few details. It helps to include:
- Whether the building will be occupied during the work
- Any specification or named product
- Access details, including height
- Asbestos survey details if the building is older
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.
What we can’t put right
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Leaking roofs, gutters or flat-roof membranes (those need a roofer)
- Faulty windows rather than failed perimeter sealant
- Cracking that needs a structural engineer to look at it
If you’re not sure, just call the office on 01277 525 020 or email the details over and we’ll give you a straight answer before you book.
