What the job involves on each surface
Internal decorators’ caulk
Caulk is easy to apply badly. A neat, consistent caulk line makes the decorators’ job quicker.
Kitchens and utility areas
Kitchen joints are sealed after fitting and before final clean. A kitchen-suitable sealant is used.
Construction mastic in Rush Green
Refurbishment work needs a slightly different approach from new build. Old beads come out completely, as fresh silicone can’t grip old, and on older buildings we ask for the asbestos survey before disturbing anything. New and existing joints then get the same preparation. Most enquiries involve cracks opening in caulked internal joints and sealant knocked or painted over by other trades, on floor and skirting junctions, window and door perimeters and cladding and panel joints. A specialist sealant contractor works differently from a general builder: on jobs in Rush Green, preparation and product choice get the time they need.
Around smaller places like Rush Green, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
Our 12-month guarantee is about workmanship, not 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.

What else we do in Rush Green
Questions we are asked in Rush Green
Can you take on a job at a hospital such as Hertford County 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.
Is Rush Green off your patch?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.
Is the mastic package guaranteed?
It carries a 12-month guarantee on our workmanship. We are also fully insured for public liability.
Will you come and look before quoting?
Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.
Can the sealant be colour-matched?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.
How do we ask for a quote?
There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.
How do you work with the site programme?
Working to your programme, we seal each area as it’s handed over. The sequence is agreed with the site manager at the start and adjusted as things change.
Maintenance after handover
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Brief following trades on areas that have been sealed
- Allow flexibility for external sealing in damp or cold weather
- Brief the final clean team to avoid blades near sealant
- Don’t schedule sealing before decorators and flooring are done
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. We can advise if a joint needs a different product.
In wet areas, a weak sanitary joint shows up quickly once the building is occupied. 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.
When to call us in Rush Green
Most mastic snags on new buildings come from sequencing rather than product. If sealant goes in before the last trades are through, it gets knocked, painted over or contaminated.
Site and facilities staff are often the first to spot these:
- Snag items on joints that need redoing before handover
- Different trades sealing to different standards
- Cracks opening in caulked internal joints
- Failed sealant in an existing building being refurbished
Hotel extensions and refits, at places such as The Station Hotel, which lies north-east of Rush Green, typically run between busy periods, so the sealing is squeezed into short windows.
Before you book anyone
- What the guarantee covers, and for how long
- How the existing material will be dealt with
- Will RAMS and insurance details be available?
- Their plan for phasing and protecting the area
Should maintenance staff do it?
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
