Construction mastic in Martin, done properly
Buyers, tenants and clients notice sealant lines long before they notice the structure. Untidy or missed joints are among the commonest snag items, and every return visit costs time. We seal so the snag list stays short, whatever the size of the scheme. Site teams most often ask us about mastic snags holding up handover and failed sealant in an existing building being refurbished, on brick and block movement joints, cladding and panel joints and window and door perimeters. Whether you call it commercial sealant work, mastic application or joint sealing, in Martin it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around smaller places like Martin, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant.

How the job changes by surface
Snagging before handover
Snagging is often the final mastic stage. Snags are cleared room by room.
Internal decorators’ caulk
Where the specification calls for it, acrylic decorators’ caulk goes on non-moving internal gaps before painting. It’s for gaps that stay still and get painted while moving joints need a flexible sealant.
Why act early in Martin
Refurbishments sometimes budget for new windows when the frames are sound and only the seal has failed. Sound frames often need only a new perimeter seal and that’s a far smaller job. If the frame is life-expired, we will tell you. For buildings around smaller places like Martin, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

How a job runs
When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself usually taking anything from a day of snagging to several weeks of plot-by-plot sealing on a phased scheme. Jobs in and around smaller places like Martin are typically planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.
- We price from the drawings, specification and programme you send.
- A fixed quote sets out the scope, the products and the sequence.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- Work follows the programme, area by area, as rooms and elevations become ready.
- Every joint is prepared, set to depth and sealed with the specified product.
- Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.
Before we start on site
- For older buildings, check the asbestos register before work
- Tell staff and tenants when we’ll be in
- Confirm the product named in the specification

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.

When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:
- Specifying the product where the designer hasn’t
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Damage to finishes by other trades after we have sealed
Not sure which it is? You can call 01277 525 020 or email us and we will tell you honestly before you book.

FAQs: Martin
Is Martin off your patch?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Which documents can you supply for work in Martin?
We’ll confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We’re CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.
How long does a job like this take?
The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Is the mastic package guaranteed?
It carries a 12-month guarantee on our workmanship. We carry five million pounds of public liability insurance.
What do you charge?
That depends on the job: quantities, access, the product and any phasing. Call for a fixed quote.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Keeping the joints sound
Cleaning and maintenance staff play a part too. Share these points with them:
- Don’t schedule sealing before decorators and flooring are done
- Ask installers to correct oversized gaps first
- Don’t force external sealing on a damp or frosty day
- Keep product details for future maintenance
Once an area is sealed, protect it from following trades. Fresh sealant needs its cure time before it’s cleaned, painted near or knocked, and that time depends on the product, temperature and joint depth.
Sanitary joints that fail early become defects soon after occupation. Water gets behind trays, vanity tops and panels. Getting the product and preparation right first time avoids that.
Cost factors for mastic packages
Your fixed quote is built from the real scope. It takes account of:
- How much there is to seal
- Specialist products, such as fire-rated or hygienic sealants
- Any access equipment needed
- The size and state of each joint
There’s no price list, since every building and every scope is different. Call for a quote.
Sending details for a quote
It doesn’t need to be a full survey. These details are enough to start:
- Clear photos of the problem areas
- Where the site is, with the postcode
- Asbestos survey details if the building is older
- Anything awkward about access or site hours

Contractors’ notes for Martin
Martin sits in one of the drier corners of the country, the South East. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so external mastic is timed for workable conditions and agreed with the site manager.
On any site in or around Martin, the mastic follows the specification and the programme. Window perimeters and facade joints around Martin need correct width, depth and backing rod as much as a neat finish.
