Questions about New Ash Green
Is a smaller place like New Ash Green outside your area?
No. Small places get the same service as large ones. London and every South East county are within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Will you take on work at estates like Heaver Farm Trading Estate, close to New Ash Green?
Yes, sites like Heaver Farm Trading Estate are within our area, along with the rest of New Ash Green. Photos and a short description are enough for a first look.
How do you work with the site programme?
The programme sets the job. Share the release dates and we will match our work to them, sealing as areas become ready.
How do you choose the sealant?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Can you come in just for snagging?
Yes. Share the list and photographs, and a fixed quote follows, then clear it to your programme.
How do I request a quote?
You can use the quote form on this site; alternatively, give us a call on 01277 525 020 or send photos by email. Photos, drawings or a joint schedule help us quote quickly.

How we handle construction mastic in New Ash Green
Since 2005 we have worked alongside main contractors, developers and fit-out firms. Quantities come off the drawings, the sequence is agreed with the site manager and the work follows the trades. To price a package in New Ash Green, send drawings and the specification through our quote form. We work on internal decorators’ caulk, sanitary and kitchen joints and window and door perimeters, and the usual reasons a site gets in touch are sealant knocked or painted over by other trades and caulk cracking where joints are moving more than expected. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in New Ash Green, that means joint design, primers and backing rod as standard.
In the countryside around places like New Ash Green, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is normally what’s needed.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Building and refurbishing in New Ash Green
New Ash Green 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 we time external mastic for dry faces and agree it with the site team. Central London is about 20 miles from New Ash Green. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, so mastic packages have to keep pace with busy programmes.
Hospital estates such as Darent Valley Hospital, 5.2 miles to the north-west of New Ash Green, 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. With historic properties like Cobham College (4.3 miles east of New Ash Green) in the area, refurbishment work often meets old masonry that needs compatible sealants. Recladding or extending a unit at a site like Heaver Farm Trading Estate (0.7 miles south-west of New Ash Green) brings panel joints and frame perimeters into the programme.
New Ash Green is about 5 miles south of Northfleet, in Kent. Anywhere in DA3, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee.

We take on mastic packages across the DA3 and TN15 postcode area, whatever the building.

How the job changes by surface
Internal decorators’ caulk
Where the specification calls for it, acrylic decorators’ caulk goes on non-moving internal gaps before painting. It’s paintable and suits gaps that don’t move.
Window and door perimeters
Frames sealed into the opening keep rain out of the reveal. We use the specified perimeter sealant, typically a low-modulus neutral-cure silicone and set the depth with backing where needed.
How the quote is worked out
Quotes vary with the job. It mainly depends on:
- Quantities, in metres or numbers
- Any access equipment needed
- The site’s rules and procedures
- Specialist products, such as fire-rated or hygienic sealants
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.
What to include in your enquiry
A few photos plus some basic facts will normally do. Please tell us:
- The type of building and who uses it
- Approximate linear metres or a joint schedule
- Access details, including height
- Asbestos survey details if the building is older
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to give us a call on 01277 525 020 or email drawings and photos with what you know.
Maintenance after handover
Once the work is signed off, a little attention goes a long way:
- Brief the final clean team to avoid blades near sealant
- Don’t force external sealing on a damp or frosty day
- Flag uneven or tapered frame gaps early
- Stick to the specified sealant rather than a generic substitute
A new structure shifts as it loses construction moisture. Flexible sealants in the right joints handle normal movement, but caulk in a joint that moves more than expected may crack. We can advise if a joint needs a different product.
One unsealed frame can let water into finished internal areas. On a new building that means remedial work after decorating and possibly a delayed handover. Checking perimeters before internal finishes go on avoids it.
Work for main contractors and building owners
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
Diagnose, treat, sign off
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Jobs in and around smaller places like New Ash Green are normally planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.

What sealant work can’t fix
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Oversized gaps that need packing or adjustment by others
- Rework caused by others damaging completed areas
- Specifying the product where the designer hasn’t
If you are not sure, just give us a call on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.
Surfaces we seal
- Floor and skirting junctions
- Brick and block movement joints
- Cladding and panel joints
- Sanitary and kitchen joints
- Window and door perimeters
- Internal decorators’ caulk
