Diagnose, treat, sign off
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. If you have more than one building in Hailsham, they can often be done on the same visit, with one quote covering them. Tell us when the building is open and we’ll plan to suit.
- We start with photos, drawings or a visit to see the joints and agree access.
- We confirm the joint type, movement and the specified product.
- Failed beads are removed in full and the joint faces cleaned.
- Primer is applied where the maker specifies it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- The finished joints are checked with you.
Before we start on site
- Clear stock, furniture or equipment away from the joints
- For older buildings, check the asbestos register before work
- Tell us your opening times and when work is allowed
Ask for a quote
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.

Facade sealing in Hailsham, done properly
Water ingress at window frames is a frequent reason facilities managers contact us. Failed perimeter sealant is a frequent cause, though that isn’t the only cause. If the evidence points away from the sealant, we say so before quoting. The enquiries we see most involve weathered facade joints that have lost their grip and weathered joints at frame-to-structure perimeters, across perimeter joints where frames meet the structure, cladding panel joints and coping and flashing joints. A specialist sealant contractor works differently from a general builder: on jobs in Hailsham, preparation and product choice get the time they need.
Developers and contractors working in Hailsham want mastic that keeps pace with the build: sealing as scaffold comes down or as each floor is decorated, and snagging before handover. Tell us the programme and we will quote to it.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Hailsham: questions and answers
Can you take on a job at a hospital such as Amberstone Hospital?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Will you fit the mastic around our build programme in Hailsham?
Yes. Send the programme and drawings, and we will plan the mastic to suit the stages. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
What about RAMS and site documents?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
What do you charge?
Every job gets its own fixed quote. To get one, give us a call on 01277 525 020 or email a schedule or drawings.
Is old mastic on our building likely to contain asbestos?
For older buildings, yes, check before work starts. The dutyholder holds the asbestos register, so ask for it before we start. If asbestos is suspected, work stops until it is tested.
Will rain stop the work?
Wet joints or temperatures outside the product’s range mean waiting. The programme allows for it and we tell you if the forecast changes things.
Which sealant will you use?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
When it isn’t the sealant
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Damp caused by condensation inside the building
- Replacing glass or failed glazing units
- Joints too narrow for the movement they take, which need redesign
Not sure which it is? You can phone 01277 525 020 or use the quote form and we’ll tell you honestly before you book.

Contractors’ notes for Hailsham
Hailsham is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager. The area within 2 miles of Hailsham holds several hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
School extensions, at buildings such as Hailsham Community College, typically run to the summer holidays, mastic included. New wings at hospitals like Amberstone Hospital, 1.5 miles to the north-east of Hailsham, bring long runs of window and panel joints to seal. Older buildings in the area around Hailsham, such as Horselunges Manor, which lies north of Hailsham, need care when sealed: the product has to suit soft or historic materials.
Hailsham is about 6 miles north of Eastbourne, in East Sussex. Anywhere in BN27, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 308 places in East Sussex. Brighton is covered too, some 17 miles away.
We cover the BN27 postcode districts for facade joints. We cover commercial and managed buildings on High Street, Market Place and Station Road and the roads nearby. You’ll find Hailsham on or near the A271 and A295, so getting applicators and materials to site is simple. Sites close to Hailsham are covered too, including Tile Hurst (1 mile north-west), Upper Horsebridge (1 mile north), Hellingly (1 mile north), Lower Horsebridge (1 mile north-west) and Magham Down (2 miles north-east).

Around Hailsham
Locally, jobs take us to sites close to The Grenadier pub and White House Academy, among other places. For rail, the closest station is Polegate station, roughly 3 miles south of the centre. Other landmarks nearby include Herstmonceux Castle (3.6 miles east) and Amberstone Hospital (1.5 miles north-east). The countryside around Hailsham includes Combe Hill.
Doing it in-house
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
How the quote is worked out
These are the things that shape the price:
- How accessible the joints are
- Location, for remote and island sites
- Phasing around occupants
- How much there is to seal
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.
Before you send an enquiry
It doesn’t need to be a full survey. These details are enough to start:
- Rough lengths or quantities, or drawings if you have them
- Where the site is, with the postcode
- The type of building and who uses it
- When you need the work done
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, speak to us on 01277 525 020 or send details through our quote form.
Why it’s worth doing now in Hailsham
If access is already up for other work, resealing at the same time makes sense. Combine it with planned external works and you only arrange access once. For businesses and landlords in Hailsham, a tidy, sound joint also matters for appearance. Fresh sealant makes a building look maintained.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

Maintenance after handover
For the best life from the joints:
- Walk the elevations once or twice a year
- Note when each elevation was last resealed
- Plan facade sealing alongside redecoration
- Insist on a full cut-out when joints are renewed
Include facade joints in your planned maintenance inspections. Watch for splits, gaps at the edges, hardening and discolouration; record the locations.
Tie resealing in with redecoration, cladding repairs or other access. One set-up for several trades saves money.
