What happens if it’s left?
Some packages split mastic across the window fitter, kitchen fitter and plumber. In practice it often means different standards, gaps in responsibility and snags nobody owns. One mastic subcontractor for the lot keeps it simple, with the same standard on every plot. Halls, stores and units around places like Rowstock may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

How we handle construction mastic in Rowstock
Since 2005 we have worked alongside main contractors, developers and fit-out firms. Quantities come off the drawings, the sequence is agreed with the site manager and the work follows the trades. To price a package in Rowstock, send drawings and the specification through our quote form. If you have caulk cracking where joints are moving more than expected and failed sealant in an existing building being refurbished, we can put it right. A specialist sealant contractor works differently from a general builder: in Rowstock, that means joint design, primers and backing rod as standard.
For a site near Rowstock, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Drawings, photos and the programme let us give a fixed quote.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Keeping the joints sound
A few simple habits keep the new joints working:
- Don’t schedule sealing before decorators and flooring are done
- Ask for joint and product checks before the package is urgent
- Ask cleaners to use soft cloths around fresh sealant
- Check frame gaps are within the sealant’s range before sealing
After we’ve sealed an area, it helps to keep other trades from damaging the joints. Fresh sealant needs its cure time before it’s cleaned, painted near or knocked; we confirm the time for each product.
One unsealed frame can let water into finished internal areas. That typically means redoing finishes in a completed area. A check of every frame before decorators start is worth the time.

Common problems we fix in Rowstock
On a live site, contamination is the biggest threat to a new joint. Dust, film adhesive, damp and grease on the joint faces prevent a proper bond.
Typical triggers for a call:
- Caulk cracking where joints are moving more than expected
- Different trades sealing to different standards
- Snag items on joints that need redoing before handover
- Frame perimeters left unsealed or poorly sealed
For contractors at a school such as Harwell Primary School, sealing has to be finished before term starts.

What the job involves on each surface
Bathrooms, en suites and washrooms
Across a block of flats or a hotel, sanitary sealing is repeated in every room. One applicator team gives the same finish everywhere, plot by plot or floor by floor.
Kitchens and utility areas
Commercial kitchens often need hygienic or food-safe sealants. We follow the specification and seal to a smooth, cleanable finish.
Your questions answered
Would you work within a site like Didcot Hospital?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Is Rowstock too small for you to travel to?
No. Places such as Rowstock are covered as much as the big towns. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
What do you charge?
We don’t publish prices, because every site is different. Send photos or drawings and we will price it at a fixed figure.
Can staff carry on working while you’re here?
In most cases, yes. We phase the work so most of the building stays in use, with each area protected and signed.
Do you take on mastic snagging only?
Yes. Share the list and photographs, and a fixed quote follows, then clear it to your programme.
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, and we confirm it before leaving site.
