About our construction mastic in Lee Gate
On a new build, the mastic package is one of the last trades through each area. We work as a mastic subcontractor to main contractors and developers on schemes in Lee Gate. Most enquiries involve sealant knocked or painted over by other trades and external joints sealed in damp or cold conditions that are now failing, across cladding and panel joints, internal decorators’ caulk and floor and skirting junctions. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Lee Gate, that means joint design, primers and backing rod as standard.
In the countryside around places like Lee Gate, 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.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

Why it’s worth doing now in Lee Gate
Patching snags as they appear can feel quicker than a proper close-out. A planned sweep of each plot or floor catches the lot in one go. Snagging can be priced as a separate stage. Converted and older buildings near places like Lee Gate tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Then we strip out anything that has failed, prepare every joint and seal it.

- Quantities are measured and a fixed price returned.
- We agree with the site team which areas come first.
- Each area is sealed when it’s released.

What the job involves on each surface
Snagging before handover
Snags typically come from damage by following trades, missed joints or poor earlier work. We price snagging as part of the package or as a separate visit.
Internal decorators’ caulk
Acrylic caulk fills internal gaps around trims, boards and frames ahead of decorating. It’s for gaps that stay still and get painted, and we use a flexible sealant where there’s movement.
Looking after the joints
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Get the mastic subcontractor involved early in the programme
- Protect sealed areas from following trades
- Ask installers to correct oversized gaps first
- Bring the mastic contractor in after the last trades are through
Expect some settlement in the first months. Flexible sealants in the right joints handle normal movement while rigid fillers and caulk can crack where movement is larger. If that happens, let us know.
A missed perimeter seal on one window can wet the reveal and the plaster inside. On a new building that means remedial work after decorating and possibly a delayed handover. A check of every frame before decorators start is worth the time.
Should maintenance staff do it?
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Common questions from Lee Gate clients
Is a smaller place like Lee Gate outside your area?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Can work at a site such as Buckinghamshire New University fit around teaching?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
Does weather affect external mastic work?
External sealing goes ahead only with a dry joint inside the product’s temperature range. Sealing in poor conditions risks adhesion failure.
How do you work with the site programme?
We seal plot by plot or floor by floor as areas are released. The sequence is agreed with the site manager at the start and adjusted as things change.
Can you fit around our working hours?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
