About our construction mastic in Crockerhill
A typical mastic package covers more than window perimeters: frame perimeters inside and out, caulking to trims and boards where the specification calls for it, sanitary silicone, kitchens, and the final snag list. One contractor for all of it keeps the responsibility in one place and gives you a consistent finish across the job. If you are dealing with sanitary sealant damaged by following trades and caulk cracking where joints are moving more than expected, we can put it right. A specialist sealant contractor works differently from a general builder: in Crockerhill, that means joint design, primers and backing rod as standard.
In the countryside around places like Crockerhill, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Questions about Crockerhill
Is Crockerhill off your patch?
No. Places such as Crockerhill are covered as much as the big towns. 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 work around term dates at a campus such as Fareham College?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Can you work to our specification?
We follow the specified sealant. Product standards such as BS EN 15651 are often named in specifications.
What do you charge?
There isn’t a price list, because every site is different. With photographs or drawings, we can give you a fixed quote.
Will you quote for a small job?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Does weather affect external mastic work?
Outside, the joint has to be dry and the temperature within the product’s limits. Damp, frost or condensation on frames can stop work.
What affects the price in Crockerhill
Your fixed quote is built from the real scope. It allows for:
- Any access equipment needed
- Whether old sealant has to be cut out first
- Location, for remote and island sites
- Joint width, depth and condition
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.
Sending details for a quote
There’s no need for a formal survey. These details are enough to start:
- Anything awkward about access or site hours
- Whether the building will be occupied during the work
- Clear photographs of the problem areas
- Drawings or a marked-up plan, if available
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.
When to call us in Crockerhill
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.
Look out for the following:
- Different trades sealing to different standards
- Existing joints on a refurb that need cutting out and resealing
- A long mastic snag list close to completion
- Missed perimeter joints on a new elevation
For contractors at a college like Fareham College (2.3 miles south of Crockerhill), perimeters and internal sealant are timed for the holidays.
What to look for in a quote
- Their public liability cover
- Do they follow the manufacturer’s priming guidance?
- How they’ll work around occupants
- Health and safety accreditation such as CHAS
What happens if it’s left?
Patching snags as they appear can feel quicker than a proper close-out. A planned sweep of each plot or floor catches the lot in one go, and avoids repeated visits. Snagging can be priced as a separate stage. Around Crockerhill, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
Why appoint us
- Fully insured, including public liability cover
- A range of standard colours, depending on the product
- Clear, fixed quotes
- Sealing commercial buildings since 2005

What the job involves on each surface
Window and door perimeters
Perimeter joints between frames and the structure are the weather line on any new building. We use the specified perimeter sealant, typically a low-modulus neutral-cure silicone, with backing rod in deeper gaps.
Snagging before handover
Snagging is often the final mastic stage. We can work through the snag list area by area.

What else we do in Crockerhill
Facades, frames and programmes in Crockerhill
Crockerhill sits close to the coast, within about 3 miles. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, so joint design, primers and product choice deserve extra care. Crockerhill has several hotels close by, all within 2 miles. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
Recladding or extending a unit at a site like Knowle Village Business Park, 1.2 miles west of Crockerhill, brings panel joints and frame perimeters into the programme. Hotels like The Old House Hotel (to the north of Crockerhill) rarely close for long, so refurbishment mastic is phased floor by floor.

Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself normally taking as long as the agreed sequence needs, which comes down to joint lengths, access and handover dates.

- First we look at the scope on site or from drawings.
- You receive a fixed quote covering scope, products and sequence.
- Paperwork is agreed and applicators are inducted on site.
- Sealing follows the programme as areas are released.

- The package is closed out, snags cleared and backed by our 12-month guarantee.
