How we handle construction mastic in Grange
On refurbishments, the mastic package normally includes cutting out old sealant as well as sealing new work. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone, and on older buildings we ask for the asbestos survey before disturbing anything. After that, the joints are prepared and sealed to the specification. Most enquiries involve external joints sealed in damp or cold conditions that are now failing and existing joints on a refurb that need cutting out and resealing, on window and door perimeters, cladding and panel joints and internal decorators’ caulk. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Grange it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
For a site near Grange, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Send drawings or photos and the programme and we will quote to suit.
Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

General trades versus a specialist
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Advice
How the quote is worked out
The price varies from site to site. It mainly depends on:
- Joint width, depth and condition
- Access and working height
- How much there is to seal
- Location, for remote and island sites
What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a quote once you have the details.
Before you send an enquiry
It doesn’t need to be a full survey. A few details are enough to get going:
- Clear photographs of the problem areas
- The site address and postcode
- Specification clauses that apply
- How the joints are reached, and at what height
Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, ring 01277 525 020 or email the details over.
What sealant work can’t fix
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:
- Glazing units that are cracked or misted
- Oversized gaps that need packing or adjustment by others
- Damage to finishes by other trades after we have sealed
If you are not sure, just phone 01277 525 020 or email drawings and photos and we will give you a straight answer.

Questions about Grange
Does your area include sites such as Beechings Way Industrial Centre, near Grange?
Yes. We cover Grange and the area around it, including industrial estates, business parks and retail parks such as Beechings Way Industrial Centre. Photos and a short description are enough for a first look.
Can being near the sea in Grange affect the sealant we need?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Can you work while the building is occupied?
In the majority of cases, yes. We phase the work so most of the building stays in use.
Can weather delay the job?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Do you take on mastic snagging only?
Yes. We clear snags by redoing joints rather than patching them, working to your handover date.
Can fire-rated sealing at service penetrations be included?
Fire-rated sealant can be included where it’s specified, installed to the product’s tested detail. The design and sign-off belong to the designer, fire engineer or building control.
Do you need construction mastic in Grange?
Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A sealant that isn’t right for the substrate or the movement will fail ahead of time. We stick to the specified product, or put any alternative to you first.
Look out for the following:
- Missed perimeter joints on a new elevation
- A mastic package split between trades with no clear owner
- Caulk cracking where joints are moving more than expected
- Failed sealant in an existing building being refurbished
Hospital estates such as Medway Maritime Hospital (1.8 miles west of Grange) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.
Before you book anyone
- Proof of insurance
- Their plan for phasing and protecting the area
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Will CSCS-carded applicators be on site?
Construction mastic around Grange: what changes locally
With the shore within about 1 mile, Grange counts as a coastal location. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Central London is about 30 miles from Grange. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes.
School extensions, at buildings such as Woodlands Primary School, typically run to the summer holidays, mastic included. When a college such as MidKent College Gillingham Campus, 1.7 miles west of Grange, builds or refurbishes, the mastic package usually has to fit around students and staff.
