Northease: questions and answers
Will you plan work around the academic year at somewhere like University of Brighton?
Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Will you take on work at estates like Cliffe Industrial Estate, close to Northease?
Yes. We cover Northease and the area around it, including industrial estates, business parks and retail parks such as Cliffe Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.
Is it okay to overlay old mastic?
No. Overlaying is a shortcut that peels away quickly. Our method is a full cut-out, cleaning, backing and a new bead.
Can you work on upper floors?
Access is planned with you before we quote. Let us know what access is in place or planned, and the quote will reflect it.
How long does a typical visit take?
It depends on the scope, but the work typically takes anything from a single day to several weeks, depending on joint lengths, access and the weather. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Will you come and look before quoting?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
About our facade sealing in Northease
Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure on commercial buildings in Northease. Coping and flashing joints are included where sealant is the specified fix. The enquiries we see most involve air leaks through failed facade joints and new sealant peeling off old mastic, across window and door perimeters, stone and brick facade joints and perimeter joints where frames meet the structure. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Northease, preparation and product choice get the time they need.
Conversions of older rural buildings near smaller places such as Northease bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is typically what’s needed.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

What the job involves on each surface
Coping and flashing joints
Coping and flashing joints are included where sealant is the specified fix. They sit in the most exposed positions on the building.
Cladding panel joints
On sealed panel systems, every joint keeps water out. Failed runs are cut out and rebuilt end to end to the correct depth.
Building and refurbishing in Northease
The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager. Central London is about 46 miles from Northease. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme.
Hospital estates such as Lewes Victoria Hospital, 2.4 miles to the north of Northease, 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. On a campus such as University of Brighton, 3.5 miles to the south-east of Northease, new teaching buildings and residences are normally built and refurbished around the academic year.
Northease is about 3 miles south of Lewes, in East Sussex. We cover commercial sites throughout Northease, whether it’s a single job or part of a planned programme. We work across 308 places in East Sussex, from busy centres to rural villages. We also cover Brighton, around 6 miles from Northease.
Postcode districts covered here: BN7. We also cover Rodmell (1 mile south-east), Iford (1 mile north-west), Kingston near Lewes (2 miles north-west), Southover (2 miles north) and Cliffe (2 miles north). Nearby towns on our patch include Eastbourne (13 miles east), Seaford (6 miles south-east), Hailsham (11 miles east), Uckfield (10 miles north-east), Newhaven (4 miles south-east) and Peacehaven (3 miles south).

Diagnose, treat, sign off
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. If others near Northease need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.
- We plan access and the order of elevations with the client.
- We only seal when joints are dry and within the product’s temperature range.
- We remove the old bead and check the edges are sound.
- Faces are cleaned, primed where needed and backed.

Related advice
Aftercare for building managers
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Ask about asbestos in pre-2000 mastic
- Note when each elevation was last resealed
- Don’t wait for a second leak before calling
- Add perimeter sealant to planned maintenance checks
Anything drilled through a facade joint breaks the seal. Ask the installer to reseal it properly with a compatible product.
In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it, and work stops until it’s tested if it’s suspected.
What else we do in Northease
Why it’s worth doing now in Northease
Every shower drives water through a split perimeter bead. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing now costs less than repairing interiors later. For buildings around smaller places like Northease, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

Signs you need facade sealing in Northease
Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.
These are often picked up first by site or facilities staff:
- Failed seals around shopfront and entrance frames
- Weathered facade joints that have lost their grip
- Water coming in around window frames
- Failed sealant on precast panel joints
Projects at colleges like Sussex Downs College (2 miles north of Northease) tend to run to term dates, so the mastic is planned tightly.
Questions to ask before you book
- Will RAMS and insurance details be available?
