Construction mastic in Coney Hall, done properly
Most of the packages we price run well beyond frames: frame perimeters inside and out, caulking to trims and boards where the specification calls for it, sanitary silicone, kitchens, and the final snag list. One contractor for all of it keeps the responsibility in one place and gives you a consistent finish across the job. We work on floor and skirting junctions, cladding and panel joints and window and door perimeters, and what we are called in for most is different trades sealing to different standards and early adhesion failures on new external joints. A single leaking joint is often how a building in Coney Hall first comes to us: we look at the rest while we are there and tell you what we find.
Construction in a London area such as Coney Hall means working on constrained sites: limited storage, booked deliveries and access shared with other trades. We fit around the programme, sealing each elevation or floor as other trades hand over.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

General trades versus a specialist
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Questions about Coney Hall
Can you cope with the access rules in a London building?
Yes. Inductions, permits and timed loading are routine for us in London. The building manager’s rules go straight into our method.
Do you take on work at healthcare sites like Bethlem Royal Hospital?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
What site paperwork can you supply?
Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Can staff carry on working while you are here?
In most cases, yes. We phase the work so most of the building stays in use, with each area protected and signed.
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.
What guarantee comes with a mastic package?
Each package is signed off with a 12-month workmanship guarantee. Damage by others after we’ve finished isn’t covered.
What the job involves on each surface
Fire-rated sealant where specified
Fire-rated sealant is one type of fire-stopping product. Collars, wraps, batts and boards are specified for other services. Tell us what records you need and we’ll confirm with the quote.
Snagging before handover
Snags normally come from damage by following trades, missed joints or poor earlier work. We price snagging as part of the package or as a separate visit.
Owners, agents and contractors
Building owners and managing agents use us on sealant work across single buildings or whole portfolios. Several sites can go on one quote, which keeps the paperwork simple.
Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
On site: what to expect
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- First we look at the scope on site or from drawings.

For contractors at a school such as Forest Academy, sealing has to be finished before term starts. Historic houses such as Addington Palace, 1.2 miles south-west of Coney Hall, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

Signs you need construction mastic in Coney Hall
On construction sites, joints typically fail early because of when they were sealed, not what was used. Sealing before decorators, flooring or other trades have finished leaves joints exposed to damage, and the joint has to be redone.
Any of the following is a good reason to get the joints checked over:
- Bath and shower joints scraped during the final clean
- Cracks opening in caulked internal joints
- Inconsistent sealant finishes from plot to plot
- Frame gaps too wide for sealant alone
Projects at colleges like Shaftesbury Nash College (to the east of Coney Hall) tend to run to term dates, so the mastic is planned tightly.
Questions to ask before you book
- Can the work be phased to keep areas open?
- Do they follow the manufacturer’s priming guidance?
- Proof of insurance
- What the guarantee covers, and for how long
Cost factors for mastic packages
These are the things that shape the price:
- Distance, for remote addresses
- Whether the work must be split into stages
- Quantities, in metres or numbers
- Backing rod, priming and other preparation
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

- Photos of the joints, close up and from further back
- Approximate linear metres or a joint schedule
