About our construction mastic in East Saltdean
Most of the packages we price run well beyond frames: frame perimeters inside and out, caulking to trims and boards where the specification calls for it, sanitary silicone, kitchens, and the final snag list. Splitting those between trades often leaves gaps in responsibility, and one applicator team gives a consistent finish. The enquiries we see most involve caulk cracking where joints are moving more than expected and sanitary sealant damaged by following trades, on floor and skirting junctions, brick and block movement joints and window and door perimeters. One point of contact handles commercial sealant work in East Saltdean from the first photos to the final walk-round, for single jobs and planned programmes alike.
Conversions around smaller places like East Saltdean often join new frames to old masonry or timber, and the sealant at those junctions has to cope with two materials that move differently.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Why act early in East Saltdean
Sealing over damaged or contaminated new joints might save a day, but it won’t last. Sealant can’t grip a contaminated or existing bead and the defect reappears in the defects period. Damaged joints are removed and resealed from clean faces. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.
The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.
Why appoint us
- 12 months’ guarantee on every job
- Sealing commercial buildings since 2005
- A Constructionline member, so easy to vet
- Colours chosen to suit frames, cladding or finishes where possible

New build and refits around East Saltdean
The sea is no more than about 1 mile from East Saltdean. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, so we check the specified product suits the exposure before the first bead. East Saltdean sits in one of the drier corners of the country, the South East. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, which is why external dates are agreed with the site manager.
Projects at schools like Saltdean Primary School work to term dates, so mastic is programmed tightly. New wings at hospitals like French Convalescent Home, 3.5 miles to the west of East Saltdean, bring long runs of window and panel joints to seal.

Common questions from East Saltdean clients
Do you cover business parks and estates near East Saltdean, such as Meridian Shopping Centre?
Yes. Our area takes in East Saltdean and its surroundings, with estates and business parks such as Meridian Shopping Centre included. Photos and a short description are enough for a first look.
Can being near the sea in East Saltdean affect the sealant we need?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Does weather affect external mastic work?
External sealing goes ahead only with a dry joint inside the product’s temperature range. Wet or cold joints cause adhesion problems, so we wait rather than redo work.
Are you fully insured?
Yes. We are fully insured, and the certificate can go with your quote.
Do you do fire-rated sealing on new builds?
Fire-rated sealing at service penetrations and linear gaps can be included where specified. Record requirements are confirmed at quote stage.
Will you stick to the specified products?
We use the product the specification names. If we think an alternative would suit better, we put it to you first.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Maintenance after handover
Regular inspection catches problems early. Specifically:
- Brief the final clean team to avoid blades near sealant
- Bring the mastic contractor in after the last trades are through
- Ask installers to correct oversized gaps first
- Keep finished joints away from paint, plaster and scrapers
Brief the sparkle clean so they don’t scrape the new joints. Blades and abrasive pads are the commonest cause of damage at the final clean.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Sealant stretched over an oversized gap won’t last. We raise them during our first walk of the area.
When to call us in East Saltdean
Frames installed with uneven gaps make perimeter sealing harder. Every product has limits on how wide a joint it can bridge and gaps beyond it need packing or adjusting by the frame installer. Better to raise it at the start than seal a joint that’s bound to fail.
Common reasons buildings call us in:
- A long mastic snag list close to completion
- External joints sealed in damp or cold conditions that are now failing
- Old sealant on a refurbishment that needs stripping before new work
- Sealant knocked or painted over by other trades
Work at a hotel such as Olde Place Hotel (to the west of East Saltdean) tends to be programmed around bookings, mastic included.

What sets the cost
We price every job individually. The main factors are:
- How much there is to seal
- The product specified
- Induction, permit and paperwork requirements
- How accessible the joints are
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
Sending details for a quote

Honest limits
We check first that sealant really is the fix. It won’t put right:
- Specifying the product where the designer hasn’t
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Defective windows, doors or glazing units (the supplier or installer’s job)
