Mastic sealing in Agar Town
Different joints need different sealants. Window perimeters and external joints often take a low-modulus neutral-cure silicone, and MS polymer sealants stick well to many substrates and often take paint, and colours are confirmed for whichever product is used. Most enquiries involve movement joints with sealant missing and the same joint failures repeated across a portfolio, across window and door perimeters on blocks, shopfronts below residential blocks and balcony and threshold joints. A single leaking joint is often how a building in Agar Town first comes to us: we look at the rest while we are there and tell you what we find.
Across Greater London, Agar Town included, the ULEZ applies, and parking and loading rules differ from street to street. For a block or estate, it helps to know where we can park and stage materials.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

When to call us in Agar Town
Topping up old mastic is a common shortcut. New sealant won’t grip failed sealant, so these repairs rarely last.
Things that usually lead to an enquiry:
- Worn sealant at communal door frames
- No planned programme for sealant
- Mastic failing across several blocks on an estate
- Patchy repairs in mismatched sealant
If your remit includes a building such as Abacus Belsize Primary School, frame and door mastic can be programmed for the holidays.

Questions we’re asked in Agar Town
Is Roman Way Industrial Estate, near Agar Town, within your area?
Yes. We cover Agar Town and the area around it, including industrial estates, business parks and retail parks such as Roman Way Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.
Will you work in a care home in Agar Town without moving residents out?
Yes. Care settings are planned area by area, at times agreed with the home. Noise and disruption are kept to a minimum.
Does the weather affect the work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Do you work for managing agents and housing associations?
Yes, that’s exactly who this service is for. We work through buildings in a planned order with dates agreed in advance.
What paperwork can you provide?
We’re CHAS accredited, a Constructionline member and carry public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
What will the job cost?
Each job is quoted on its own details. For yours, give us a call on 01277 525 020 or use the quote form with a description of the work.
Is it fine to apply new sealant on top of old?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
What affects the price in Agar Town
To price the job, we consider:
- Site requirements such as inductions and permits
- Location, for remote and island sites
- Any access equipment needed
- Backing rod, priming and other preparation
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.
What to include in your enquiry
It doesn’t need to be a full survey. These details are enough to start:
- The type of building and who uses it
- Anything awkward about access or site hours
- The site address and postcode
- Whether an asbestos survey exists
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to ring 01277 525 020 or send details through our quote form with what you know.
For managing agents and facilities managers
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.
General trades versus a specialist
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
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.
How a job runs
Site rules come first: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, we take the joints in the sequence agreed with you. For a job in Agar Town, access comes first: 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’ll schedule to suit.
- We inspect each building and record the joints that have failed.
- You get a fixed quote, per block or for the whole programme.
- We agree the programme and dates with you.
- Failed sealant is removed and the faces prepared.
- Joints are resealed and tooled.
- Each building is checked and signed off with the 12-month guarantee.
Getting the site ready
- Have the specification and drawings to hand
- Let building users know which areas are affected
- Agree which areas must stay open
