Construction mastic in Lidsing
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Construction mastic in Lidsing, done properly
The programme rarely stands still, so the mastic package has to flex with it. We agree a sequence at the start and adjust it as the site manager releases areas and we don’t seal before other trades have finished in an area. That keeps the work right first time and saves rework. If you have external joints sealed in damp or cold conditions that are now failing and frame perimeters left unsealed or poorly sealed, we can put it right, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Lidsing, that means joint design, primers and backing rod as standard.
In the countryside around places like Lidsing, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
A 12-month guarantee applies to all our work. Should something we installed fail, ring 01277 525 020 or send details through our quote form and we will come back to it.

Why it’s worth doing now in Lidsing
On a refurbishment, there’s a choice between resealing existing frames and replacing them. If the frame is in good order, cutting out and resealing the perimeter can be all it needs. We’ll say so if a frame itself is the problem. Halls, stores and units around places like Lidsing may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

- Quantities, in metres or numbers
A quote for mastic packages depends on how many there are, their condition and the access. Call for a quote.

Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, phone 01277 525 020 or use the quote form.
How the job changes by surface
Snagging before handover
Snagging is often the final mastic stage. We can work through the snag list area by area.
Internal decorators’ caulk
Caulking is often done in a hurry by whoever’s on site. Done properly, it saves decorators time and gives a clean line and keeps the snag list down.
Common questions from Lidsing clients
Would you work within a site like Spire Alexandra Hospital?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is Lidsing too small for you to travel to?
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’ll plan the job to need as few trips as possible.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
Will you quote for a small job?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
How long does a typical visit take?
We plan the time on site around your programme and access. You’ll have an expected duration with the quote.
Can fire-rated sealing at service penetrations be included?
It can be part of the package where specified. Record requirements are confirmed at quote stage.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Common problems we fix in Lidsing
Wide, tapered or inconsistent gaps around frames are a common problem. Every product has limits on how wide a joint it can bridge and gaps beyond it need packing or adjusting by the frame installer. Better to raise it at the start than seal a joint that’s bound to fail.
Any of the following is a good reason to get the joints checked over:
- Snag items on joints that need redoing before handover
- Existing joints on a refurb that need cutting out and resealing
- Sealant knocked or painted over by other trades
- Frame perimeters left unsealed or poorly sealed
Extensions at sites like Spire Alexandra Hospital (1.6 miles west of Lidsing) normally sit beside working departments, and the mastic follows strict access rules.
Comparing quotes
- How the joint faces will be prepared and primed
- Which product they’ll use, and why it suits the joint
- Are they CHAS accredited or on Constructionline?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
Doing it in-house
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Construction mastic in Lidsing: the local picture
Lidsing 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. At about 31 miles from central London, Lidsing is within reach of the capital. 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.
Building work at universities like University for the Creative Arts - Rochester, 4 miles north-west of Lidsing, is often timed for the summer, mastic included. School extensions, at buildings such as Swingate Primary School, typically run to the summer holidays, mastic included.
Lidsing is about 2 miles south-east of Chatham, in Kent. Anywhere in ME7, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Across Kent, 931 places are covered, Lidsing among them. London is covered too, some 31 miles away.
