How we handle facade sealing in Bexleyheath
Facade joints are the line of defence between the weather and the building fabric. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We remove failed sealant and install a new bead chosen for the joint and how far it moves. We work on shopfront frames, stone and brick facade joints and cladding panel joints, and the usual reasons a site gets in touch are perimeter sealant that has split or peeled away and discoloured or dirty facade joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Bexleyheath it comes down to the same thing: the right product in a properly prepared joint.
Construction in a London area such as Bexleyheath means working on constrained sites: small compounds, delivery slots and shared hoists and scaffold. Mastic is usually one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Questions about Bexleyheath
Can work at a site such as University of Greenwich Avery Hill Campus fit around teaching?
Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Is a hospital such as Erith and District Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Will your applicators have CSCS cards?
Yes. Our applicators hold CSCS cards.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
Can the building stay open while you work?
In most cases, yes. Phased work can be planned so areas stay in use.
When can you be on site?
Mention the site’s hours and access windows in your enquiry, and we will plan around them. Our office runs Monday to Friday, 8am until 5pm.
Aftercare for building managers
Once the work is signed off, a little attention goes a long way:
- Keep the sealant details on the building file
- Brief window cleaners about newly sealed joints
- Share access with other external trades
- Insist on a full cut-out when joints are renewed
Hold back any cleaning crew until the joints have had their stated cure time. Keep high-pressure jets and strong chemicals away from new sealant.
Check older buildings for asbestos before disturbing old mastic. Some older mastics contain it, and if it’s suspected, we stop until it has been tested.
When to bring in a specialist
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
How a job runs
Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Planning a London job such as one in Bexleyheath starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we will schedule to suit.
- We look at the joints, the drawings and the access before pricing.
- Failed sealant is cut out along its full length.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- We walk the finished joints with you before handing over.
What we need from you
- Confirm the product named in the specification
- Let building users know which areas are affected
- Flag any permit to work we’ll need

Advice
What we’re called out for in Bexleyheath
Product choice matters: an acetoxy cure can mark stone or corrode some metals, and interior products break down outdoors. Neutral-cure, facade-grade products are what most external joints need.
It’s worth sending us details if you spot any of the following:
- Facade joints cracked through the middle
- Failed sealant on precast panel joints
- Old perimeter mastic that has dried out
- Discoloured or dirty facade joints
On a healthcare site such as Erith and District Hospital, 1.7 miles to the north-east of Bexleyheath, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
What to look for in a quote
- How the existing material will be dealt with
- Whether their applicators hold CSCS cards
- Are they CHAS accredited or on Constructionline?
- What the guarantee covers, and for how long
Honest limits
Honesty saves time and money. New sealant won’t cure:
- Damaged frames that need replacing
- Water getting in through cracked render or porous masonry
- Work on the window or framing system itself

Facade sealing in Bexleyheath: the local picture
A 2-mile radius around Bexleyheath takes in several hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. The ULEZ covers the whole of Greater London, Bexleyheath included, so site vehicles need to meet its standards or pay the daily charge. Add booked deliveries and tight storage, and the mastic package needs planning with the site team.
For contractors refurbishing units at places like Old Bexley Business Park, 1.3 miles south-east of Bexleyheath, the mastic covers cladding panels, roller-door and window perimeters. When a college such as Rose Bruford College, 1.9 miles south-west of Bexleyheath, builds or refurbishes, the mastic package usually has to fit around students and staff.
