How we handle construction mastic in Crowmarsh Gifford
Mastic tends to be one of the final packages before handover. We work as a mastic subcontractor to main contractors and developers, sealing plot by plot or floor by floor as areas are released. We work on floor and skirting junctions, internal decorators’ caulk and sanitary and kitchen joints, and what we are called in for most is mastic snags holding up handover and frame perimeters left unsealed or poorly sealed. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Crowmarsh Gifford, that means joint design, primers and backing rod as standard.
In the countryside around places like Crowmarsh Gifford, 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.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Surface by surface
Kitchens and utility areas
Worktop upstands, sinks and splashbacks are sealed once the kitchen is fitted. A kitchen-suitable sealant is used, food-safe where food contact is possible.
Bathrooms, en suites and washrooms
Across a block of flats or a hotel, sanitary sealing is repeated in every room. A single team keeps the standard consistent.

When it isn’t the sealant
Being straight saves everyone time. New sealant won’t cure:
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Frames fitted out of tolerance
- Designing joint widths or choosing the specification (that sits with the designer)
If in doubt, call the office on 01277 525 020 or use the quote form and we will say what we think.
Joints and surfaces we work on
- Window and door perimeters

Advice
Questions we’re asked in Crowmarsh Gifford
Is a smaller place like Crowmarsh Gifford outside your area?
No. Places such as Crowmarsh Gifford are covered as much as the big towns. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.
Can you take on a job at a hospital such as Wallingford Community Hospital?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
Can one quote cover more than one building?
Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.
What does a mastic package normally include?
Inside and out: frame perimeters, movement joints, caulk where called for, sanitary and kitchens.
How long does a typical visit take?
It depends on the scope, but the work typically takes whatever the programme allows, since the work follows the trades as areas are released. Larger or phased jobs take longer, and we will give you a timescale with the quote.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Can fire-rated sealing at service penetrations be included?
Fire-rated sealing at service penetrations and linear gaps can be included where specified. Tell us what records you need and we will confirm with the quote.

Keeping the joints sound
After handover, these steps help:
- Bring the mastic contractor in after the last trades are through
- Keep product details for future maintenance
- Brief following trades on areas that have been sealed
- Brief the final clean team to avoid blades near sealant
At handover, keep the product details with the O&M information. Future maintenance is easier when the products are known, and tells you what to reseal with. Tell us what records you need and we’ll confirm with the quote.
Leaving the mastic snag list to the end squeezes everyone. Clearing snags area by area spreads the work out.
Doing it in-house
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will 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.
