Different surfaces, different methods
Bathrooms, en suites and washrooms
Sanitary joints around baths, showers, basins and WCs need anti-mould sanitary silicone. Each joint is prepared, sealed and finished with a neat tooled line.
Fire-rated sealant where specified
Fire-rated sealant forms part of some packages, installed to the product’s tested detail where it is specified. The design and sign-off of fire stopping sit with the designer, principal designer or fire engineer.
About our construction mastic in Shenington
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, so applicators arrive when areas are genuinely ready. That keeps the work right first time and saves rework. Site teams most often ask us about oversized or tapered gaps around new frames and bath and shower joints scraped during the final clean, across brick and block movement joints, window and door perimeters and floor and skirting junctions. Facilities teams, main contractors and managing agents in Shenington tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Sites around smaller places like Shenington can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Drawings, photos and the programme let us give a fixed quote.
Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Keeping the joints sound
Regular inspection catches problems early. Specifically:
- Get the mastic subcontractor involved early in the programme
- Flag uneven or tapered frame gaps early
- Brief following trades on areas that have been sealed
- Stick to the specified sealant rather than a generic substitute
Tell the builders’ clean team which areas have new sealant. Blades and abrasive pads are the commonest cause of damage at the final clean so keep them off the joints.
In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Leaks behind showers and basins damage finishes and floors, and the repair falls into the defects period. Getting the product and preparation right first time avoids that.
When to call us in Shenington
Three-sided adhesion is a frequent fault on new work. Bonded to the base of the joint and both sides, sealant can’t stretch evenly.
Any of the following is a good reason to get the joints checked over:
- Window and door perimeters that won’t pass inspection
- Snag items on joints that need redoing before handover
- Inconsistent sealant finishes from plot to plot
- Internal caulk splitting as the building dries out
When a school such as Shenington Church of England Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.
What to look for in a quote
- Their plan for phasing and protecting the area
- How long is the guarantee, and what does it include?
- How the joint faces will be prepared and primed
- Will failed sealant be removed rather than covered?
What sets the cost
To price the job, we consider:
- Location, for remote and island sites
- Induction, permit and paperwork requirements
- Whether the work must be split into stages
- The size and state of each joint
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.
Details that help us quote
We can often quote from photos and a few details. Please tell us:
- When you need the work done
- Whether the building will be occupied during the work
- Clear photos of the problem areas
- Access details, including height
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

How a job runs
On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work normally takes a few days on a modest refurbishment and longer on multi-plot or multi-storey schemes. Rural sites near Shenington may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- First we take quantities off the drawings and read through the specification.
- A fixed quote sets out the scope, the products and the sequence.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- We seal each plot or floor as it’s released to us.
- Each joint is prepared, backed to depth and sealed in the product the specification names.
- Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.
What we need from you
- Tell us which areas need to stay in use
- Point out parking and an unloading spot
- For older buildings, check the asbestos register before work

Sites and facades in and around Shenington
Shenington sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack.
When a college such as Wroxton College (3 miles east of Shenington) builds or refurbishes, the mastic package usually has to fit around students and staff. Historic houses such as Upton House (to the north of Shenington) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

Your questions answered
Is Shenington too small for you to travel to?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Can you take on a job at a hospital such as Horton General Hospital?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Does the weather affect the work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
What do you charge?
It depends on the job: quantities, access, the product and any phasing. Call for a quote.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
Do you install fire-rated sealant as part of a package?
We install fire-rated sealant where it is the specified product, working to the specification and the manufacturer’s installation guidance. We will flag if the detail needs a different product.
Will you quote for a small job?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
