How the job changes by surface
Kitchens and utility areas
Worktop upstands, sinks and splashbacks are sealed once the kitchen is fitted. The sealant is a kitchen-grade product and hygienic or food-safe grades wherever food contact is possible.
Snagging before handover
Snags usually come from damage by following trades, missed joints or poor earlier work. We price snagging as part of the package or as a separate visit.
How we handle construction mastic in Crumbles
Refurbishment work needs a slightly different approach from new build. Old beads come out completely, as fresh silicone can’t grip old and the asbestos survey is checked first on older stock. New and existing joints then get the same preparation. We work on sanitary and kitchen joints, brick and block movement joints and window and door perimeters, and the usual reasons a site gets in touch are old sealant on a refurbishment that needs stripping before new work and oversized or tapered gaps around new frames. Whoever orders the work in Crumbles, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Around smaller places like Crumbles, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What else we do in Crumbles
What sealant work can’t fix
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Damage to finishes by other trades after we’ve sealed
- Approving fire stopping as compliant
If in doubt, ring 01277 525 020 or use the quote form and we will say what we think before you book.

Owners, agents and contractors
We work for building owners and managing agents on everything from one building to a spread of sites around Crumbles. Several sites can go on one quote, so there’s one set of paperwork to deal with.
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.
General trades versus a specialist
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
FAQs: Crumbles
Will you take on work at estates like Sovereign Harbour Village Retail Park, close to Crumbles?
Yes. We cover Crumbles and the area around it, including industrial estates, business parks and retail parks such as Sovereign Harbour Village Retail Park. To start, just phone 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
Can work at a site such as University of Brighton Eastbourne Campus fit around teaching?
Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Is the mastic package guaranteed?
It’s backed by our 12-month guarantee on the workmanship. Protecting sealed areas from following trades helps avoid damage.
Do your applicators hold CSCS cards?
Our applicators hold CSCS cards, and we are CHAS accredited and a Constructionline member. We’re also fully insured, with five million pounds of public liability cover.
Does the weather affect the work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Can you work plot by plot or floor by floor?
Our work is sequenced around the programme. Each plot, floor or elevation is sealed when it’s ready.
How do I request a quote?
You can use the quote form on this site; alternatively, give us a call on 01277 525 020 or use the quote form. Include photographs or drawings if you have them.
How a job runs
On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work typically takes a day or two on a small fit-out and several weeks on a large multi-storey package. Jobs in and around smaller places like Crumbles are usually planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- First we look at the scope on site or from drawings.
- A fixed quote sets out scope, products and phasing.
- Paperwork is agreed and applicators are inducted on site.
- Sealing follows the programme as areas are released.
- Any frame gaps or issues outside our scope are flagged to the site team.
- Final snagging is completed and the 12-month guarantee applies.
Getting the site ready
- Make sure the joints can be reached
- Let us know about inductions and permits
- Tell staff and tenants when we’ll be in

Advice
Sites and facades in and around Crumbles
Crumbles lies within about 1 mile of the sea. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, and the sealant, primer and backing need choosing with that in mind. Crumbles is about 52 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme.
Work at a hotel such as Bay Hotel, 1.3 miles to the north-east of Crumbles, tends to be programmed around bookings, mastic included. For a contractor working at a hospital such as Eastbourne District General Hospital, 2.9 miles to the west of Crumbles, perimeter and facade sealing is planned around patients and deliveries.

If you need construction mastic in BN23, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed.

Common problems we fix in Crumbles
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, so they end up back on the snag list.
It’s worth sending us details if you spot any of the following:
- New external sealant already peeling away
- Old sealant on a refurbishment that needs stripping before new work
- Sealant knocked or painted over by other trades
- Frame gaps too wide for sealant alone
For contractors on a campus like University of Brighton Eastbourne Campus, 4.1 miles south-west of Crumbles, facade and perimeter sealing has to fit around students and term dates.
Questions to ask before you book
- Health and safety accreditation such as CHAS
- Whether primer will be used where the manufacturer specifies it
- Can the work be phased to keep areas open?
- Their public liability cover
