What sealant work can’t fix
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Joints damaged after sign-off by following trades
- Glazing units that are cracked or misted
- Designing joint widths or choosing the specification (that sits with the designer)

Construction mastic in Great Horkesley
A typical mastic package covers more than window perimeters: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. Splitting those between trades often leaves gaps in responsibility and gives you a consistent finish across the job. We work on internal decorators’ caulk, window and door perimeters and sanitary and kitchen joints, and the failures we’re asked to look at most are cracks opening in caulked internal joints and bath and shower joints scraped during the final clean. Most enquiries from Great Horkesley start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
For a contractor on a smaller site near Great Horkesley, one mastic visit at the right stage saves return trips. Let us know the key stages and we will time the work so nothing waits on us.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Questions we’re asked in Great Horkesley
Does your area include sites such as Turner Rise Retail Park, near Great Horkesley?
Yes, sites like Turner Rise Retail Park are within our area, along with the rest of Great Horkesley. Send details of the unit and the work through our quote form for a quick quote.
Can you work around term dates at a campus such as University of Essex?
Yes, holiday working periods are the norm on campus jobs. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
What does a mastic package typically include?
The scope comes from the specification and drawings, but most packages include frame perimeters, sanitary and kitchen joints, caulking where specified and a snagging pass.
Which sealant will you use?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Can the sealant be colour-matched?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
What about RAMS and site documents?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
General trades versus a specialist
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
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.
What the job involves on each surface
Window and door perimeters
Frames sealed into the opening keep rain out of the reveal. They’re sealed with a low-modulus neutral-cure silicone or another product named in the specification, with backing rod in deeper gaps.
Bathrooms, en suites and washrooms
Sanitary joints around baths, showers, basins and WCs need anti-mould sanitary silicone. Joints are cleaned, sealed and tooled neatly, and any bath is loaded with water first where that’s the agreed method.
What we’re called out for in Great Horkesley
On construction sites, joints normally fail early because of when they were sealed, not what was used. If sealant goes in before the last trades are through, it gets knocked, painted over or contaminated, and the joint has to be redone.
Site and facilities staff are often the first to spot these:
- Mastic snags holding up handover
- Sanitary sealant damaged by following trades
- Missed perimeter joints on a new elevation
- Caulk cracking where joints are moving more than expected
Hospital estates such as Cygnet Hospital Colchester, 0.7 miles south-east of Great Horkesley, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.
Questions to ask before you book
- How long is the guarantee, and what does it include?
- Which product they’ll use, and why it suits the joint
- Their pre-qualification and accreditations
- What site paperwork they can supply

After the work
For the best life from the joints:
- Ask cleaners to use soft cloths around fresh sealant
- Don’t force external sealing on a damp or frosty day
- Bring the mastic contractor in after the last trades are through
- Keep product details for future maintenance
At handover, keep the product details with the O&M information. That helps the building owner maintain the joints later. Tell us what records you need and we will confirm with the quote.
Snag items left to the last week put handover at risk. Clearing snags area by area spreads the work out.
