Diagnose, treat, sign off
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes whatever the programme allows, since the work follows the trades as areas are released, and our waste is bagged and taken away as we go. Rural sites near Lower Basildon may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

Construction mastic for commercial buildings in Lower Basildon
External mastic depends on the weather in a way most internal trades don’t. Cold or damp mornings, frost and condensation on frames can all hold external sealing up, so we plan elevations with the forecast and the programme in mind. Internal areas can normally carry on while the outside waits. If you are dealing with bath and shower joints scraped during the final clean and perimeter gaps outside the sealant’s range, we can help, on internal decorators’ caulk, cladding and panel joints and brick and block movement joints alike. Searching for sealant specialists in Lower Basildon? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Construction in and around smaller places such as Lower Basildon is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

When something else is needed
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Damage to finishes by other trades after we have sealed
- Specifying the product where the designer hasn’t
If you’re not sure, just ring 01277 525 020 or email drawings and photos and we will give you a straight answer.
Surfaces we seal
- Internal decorators’ caulk
- Sanitary and kitchen joints
- Window and door perimeters
- Floor and skirting junctions
- Cladding and panel joints
- Brick and block movement joints
How the job changes by surface
External facade and movement joints
Brickwork, blockwork and panel movement joints need a sealant with the right movement capability. We set the depth with backing rod to avoid three-sided adhesion.
Bathrooms, en suites and washrooms
On multi-unit schemes, consistency matters across hundreds of bathrooms. One applicator team gives the same finish everywhere.
Aftercare for building managers
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Use the product the specification names
- Get the mastic subcontractor involved early in the programme
- Keep scrapers and abrasive pads off new beads
- Flag uneven or tapered frame gaps early
Any damage after we have finished should go on the snag list straight away. We can return to clear snags before handover.
Sanitary joints that fail early become defects soon after occupation. Water gets behind trays, vanity tops and panels, leaving the remedial work to the contractor. Getting the product and preparation right first time avoids that.
Leave it or put it right?
Clearing snags piecemeal is tempting when handover is close. But one planned snagging pass through each area usually clears more for less disruption, and avoids repeated visits. Snagging can be priced as a separate stage. One visit to deal with every failing joint makes more sense than several trips to a place like Lower Basildon, rather than one at a time. Photos of every joint help us quote for the whole job.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

Questions about Lower Basildon
Can you keep pace with our programme in Lower Basildon?
Yes. The mastic is planned around your key stages. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
What site paperwork comes with a job in Lower Basildon?
Whatever your site asks for, from RAMS to CSCS details, is confirmed when we quote. We hold £5m public liability insurance, are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded.
Do you install fire-rated sealant as part of a package?
We install fire-rated sealant where it is the specified product to the tested detail. If the detail calls for collars, wraps or batts instead, we’ll tell you.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
What do you charge?
It depends on the job: quantities, access, the product and any phasing. Call for a fixed quote and we’ll price it properly.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and we’ll price the work to it.
Will you come and look before quoting?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit before quoting.
