Leave it or put it right?
A cheaper sealant can look like an easy saving on a large package. A failed joint in the defects period costs far more than the product difference, especially externally. We price the specified product and will tell you plainly where an alternative would or wouldn’t work. In a London building, a failed joint rarely affects only one party. Dealing with it early is simpler for everyone.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
Why us?
- Workmanship guaranteed for 12 months
- A fixed quote before work starts
- Products installed to the manufacturer’s instructions
- Colour agreed before work starts

Construction mastic in Newington Green
A typical mastic package covers more than window perimeters: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. Splitting those between trades often leaves gaps in responsibility and gives you a consistent finish across the job. If you’re dealing with external joints sealed in damp or cold conditions that are now failing and a long mastic snag list close to completion, we can put it right. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Newington Green is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Construction in a London area such as Newington Green 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.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, call the office on 01277 525 020 or email the details over and we will come back to it.

How the job changes by surface
Snagging before handover
Snagging is often the final mastic stage. We can work through the snag list area by area and damaged joints are redone rather than patched.
Bathrooms, en suites and washrooms
On multi-unit schemes, consistency matters across hundreds of bathrooms. A single team keeps the standard consistent.
Aftercare for building managers
Regular inspection catches problems early. In particular:
- Ask installers to correct oversized gaps first
- Brief following trades on areas that have been sealed
- Don’t schedule sealing before decorators and flooring are done
- Ask cleaners to use soft cloths around fresh sealant
Brief the sparkle clean so they don’t scrape the new joints. Scrapers used on frames and worktops can nick or lift a new bead.
External joints sealed in poor weather are a common cause of early failure. Holding off until conditions suit avoids callbacks.

Your questions answered
Do you cover business parks and estates near Newington Green, such as Frogmore Industrial Estate?
Yes. We cover Newington Green and the area around it, including industrial estates, business parks and retail parks such as Frogmore Industrial Estate. A few photographs and the unit address let us price the work.
Will you plan work around the academic year at somewhere like London Metropolitan University?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Will you quote for a small job?

Do your applicators hold CSCS cards?
CHAS and Constructionline are both in place, and our applicators hold CSCS cards. Public liability insurance is in place.
Do you seal on top of existing sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
How soon can the area be used again?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.
Do you take on mastic snagging only?
Yes. Send the snag list or photographs and we’ll price it.
When to bring in a specialist
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
