Construction mastic in Biggin, done properly
The programme rarely stands still, so the mastic package has to flex with it. The sequence is set with the site team and updated as plots or floors are handed over and we don’t seal before other trades have finished in an area. Sealing too early only means coming back once others have damaged it. Most enquiries involve sealant knocked or painted over by other trades and mastic snags holding up handover, across window and door perimeters, brick and block movement joints and sanitary and kitchen joints. For commercial sealant work in Biggin, you deal with one contact from quote to sign-off, whether it’s one building or several.
Sites around smaller places like Biggin can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Send drawings or photos and the programme and we will quote to suit.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant.

Leave it or put it right?
Patching snags as they appear can feel quicker than a proper close-out. But one planned snagging pass through each area normally clears more for less disruption. Snagging can be priced as a separate stage. Converted and older buildings near places like Biggin tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
A quote for mastic packages depends on quantities, condition and access, and any specification that applies. Call for a quote.

Biggin: questions and answers
Do you take on work at healthcare sites like Gravesham Community Hospital?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Does the sea air around Biggin change the choice of sealant?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We check the specified product suits the exposure and pay close attention to preparation.
Can you work to our specification?
Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.
How do we ask for a quote?
The quote form is the simplest route, though you can also phone 01277 525 020 or send photos by email. Photos, drawings or a joint schedule help us quote quickly.
How many days will you need on site?
It depends on the scope, but the work normally takes whatever the programme allows, since the work follows the trades as areas are released. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
How long before the joints can be used?
We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Construction mastic around Biggin: how the place shapes the job
Biggin is within about 2 miles of the coast. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so joint design, primers and product choice deserve extra care. At about 20 miles from central London, Biggin is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand.
New units and refits on sites such as Star Industrial Estate (to the north of Biggin) need their panel and perimeter joints sealed to the specification. Further education sites such as USP College (1.1 miles north-west of Biggin) are extended and refurbished from time to time, with mastic often programmed into the summer break. Projects at schools like Tilbury Pioneer Academy work to term dates, so mastic is programmed tightly.
Biggin is about 2 miles east of Grays, in Thurrock. Across the RM16 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Biggin is one of 27 places we cover in Thurrock. For work in that direction, see our London page, about 20 miles away.

What the job involves on each surface
Fire-rated sealant where specified
Not every penetration suits a sealant. Collars, wraps, batts and boards are specified for other services so we will flag where the detail needs something different. Tell us what records you need and we’ll confirm with the quote.
Window and door perimeters
Inside, a paintable sealant or decorators’ caulk is used where the joint doesn’t move much. We follow what’s specified.
Looking after the joints
Problems stay small when the joints are checked regularly. Specifically:
- Ask installers to correct oversized gaps first
- Note which sealant went where at handover
- Bring the mastic contractor in after the last trades are through
- Plan external elevations with the weather in mind
Record which products went where in the handover file. Future maintenance is easier when the products are known. Tell us what records you need and we’ll confirm with the quote.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Filling a wide gap with sealant alone sets up a failure. We flag them as soon as we see them.
When something else is needed
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:
- Specifying the product where the designer hasn’t
- Frame gaps too wide for sealant, which the installer needs to correct
- Joints damaged after sign-off by following trades
If in doubt, call 01277 525 020 or email the details over and we’ll say what we think.

Diagnose, treat, sign off
Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Jobs in and around smaller places like Biggin are usually planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- First we take quantities off the drawings and read through the specification.
- You receive a fixed quote listing scope, products and phasing.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- Areas are sealed plot by plot or floor by floor as the trades hand them over.
- Every joint is prepared, set to depth and sealed with the specified product.
- We close out snagging and hand over with a 12-month guarantee.
Before we start on site
- Warn occupants and staff about the work
- Send asbestos survey details if the building is pre-2000
- Have the specification and drawings to hand

Doing it in-house
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
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.
