Mastic sealing for Grange sites
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Maintenance after handover
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Share your contractor requirements early
- Log resealing dates block by block
- Make it easy for occupiers to report draughts
- Plan resealing building by building rather than complaint by complaint
Protect entrance and corridor joints from knocks where possible. Damage at low level is the most common reason communal joints fail early.
One failed perimeter typically means others on the same building are close so a single failure is a sign to check the rest. Doing them together saves going back again and again.
Mastic sealing in Grange, done properly
We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. Many prefer a planned programme to one-off visits, with each block quoted and scheduled in turn. We work on balcony and threshold joints, shopfronts below residential blocks and external wall and movement joints, and the usual reasons a site gets in touch are occupiers reporting cold air round windows and movement joints with sealant missing. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Grange, preparation and product choice get the time they need.
Around smaller places like Grange, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

What happens if it’s left?
A bead run over old mastic can look like a repair. It doesn’t bond and normally fails within a short time. Cutting out and resealing properly does it once. For buildings around smaller places like Grange, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.
A quote for mastic joints depends on how many there are, their condition and the access, plus any specification you are working to. Ask us for a fixed quote.

Blocks and managed buildings in Grange
With the shore within about 1 mile, Grange counts as a coastal location. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first, and they deserve more regular inspection. Grange lies roughly 30 miles out from central London. Managed blocks of flats are a big part of commuter-belt property; their frame mastic often ages block-wide.
Site managers at schools like Woodlands Primary School can fit frame mastic into the summer works. Student accommodation around universities such as University of Greenwich - Medway (to the north-west of Grange) is usually managed block by block, which suits a planned mastic programme. Buildings close to stations like Gillingham (Kent) station (1.3 miles west of Grange) are often flats over shops, with frame mastic to keep sound.
Grange is about 1 mile north of Gillingham, in Medway. Anywhere in ME7, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 54 places in Medway. London is covered too, some 30 miles away.
Commercial sites across ME7 and ME8 are covered. For a building on Grange Road, Lower Featherby Road and Odo Rise or nearby, we can quote for mastic joints. If your building is just outside Grange, we cover Lower Twydall (1 mile south-east), Twydall (1 mile south), Gillingham (1 mile south), Darland (2 miles south-west) and Hale (2 miles south-west). A short drive away, we cover Chatham (3 miles south-west), Rochester (4 miles west), Strood (4 miles west), Park Wood (3 miles south), Lordswood (4 miles south-west) and Hoo St Werburgh (3 miles north).

Common questions from Grange clients
Is Grange too far out for you?
No. Places such as Grange are covered as much as the big towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Our building in Grange is near the coast: does that change the sealant?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Can you send RAMS and CSCS details before starting?
Our credentials include CHAS, Constructionline and public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Is it fine to apply new sealant on top of old?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
How long does a typical visit take?
The duration is planned around your programme and the access we are given. You will have an expected duration with the quote.
Will you quote for a small job?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Diagnose, treat, sign off
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Rural sites near Grange may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

What sets the cost
To price the job, we consider:
- How accessible the joints are
- The site’s rules and procedures
- Joint width, depth and condition

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
