Facade sealing near Seaford
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
After the work
Cleaning and maintenance staff play a part too. Share these points with them:
- Keep the sealant details on the building file
- Check that rainwater leaves the facade the way it was designed to
- Don’t wait for a second leak before calling
- Check the asbestos register before old mastic is disturbed
After heavy weather, check vulnerable elevations for signs of water inside. An early report typically means a small reseal rather than a bigger repair.
Check older buildings for asbestos before disturbing old mastic. Some older mastics contain it, and work stops until it’s tested if it’s suspected.
Facade sealing in Seaford
Some clients need every window on a block resealed; others need a few leaking frames sorted. Either way, the method is the same: cut out, clean, back, prime where needed and seal. A 12-month guarantee applies to our workmanship. If you have facade joints cracked through the middle and unsightly perimeter sealant on a visible elevation, we can help. Facilities teams, main contractors and managing agents in Seaford tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Older town-centre buildings in places like Seaford are often converted to new uses or extended, which puts new frames and panels against old brick, stone or render. Getting the product and primer right for both faces is what keeps those joints sound.

Site staff or a sealant specialist?
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

How the job changes by surface
Cladding panel joints
Panel joints on cladding and rainscreen systems take movement every day. The sealant has to match the movement and the panel finish, often a low-modulus silicone or hybrid.
Coping and flashing joints
Sometimes the coping or flashing itself has failed. Where the issue isn’t the sealant, we say so.
Why deal with it now?
Failed joints let in more than water: occupants notice draughts and cold spots around windows. A new seal closes the gap for both. In Seaford, as anywhere, the simplest time to fix a failed joint is before it leaks. Once water gets in, there’s drying out and making good as well.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Seaford: questions and answers
Is hospital work, at somewhere like Chailey Heritage Marine Hospital, something you do?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Will you plan work around the academic year at somewhere like University of Brighton?
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.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
What type of sealant goes on window perimeters?
Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others.
What will the job cost?
Every job gets its own fixed quote. To get one, ring 01277 525 020 or email a schedule or drawings with a description of the work.
Can you quote from photos?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit.
Which sealant will you use?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
On site: what to expect
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and we clear our waste as we work. In a town such as Seaford, most jobs are single buildings. We start with your photographs, drawings or a site visit, then send a fixed quote.
- 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.
- Facade-grade sealant goes in and is tooled to a tidy concave profile.
- We hand over with our 12-month workmanship guarantee.
Getting the site ready
- Confirm the product named in the specification
- Point out parking and an unloading spot
- Make sure the joints can be reached

Facades, frames and programmes in Seaford
The sea is no more than about 1 mile from Seaford. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so we check the specified product suits the exposure before the first bead. Seaford 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.
Building work at universities like University of Brighton (to the north-west of Seaford) is often timed for the summer, mastic included. School extensions, at buildings such as Seaford Primary School, typically run to the summer holidays, mastic included. On a healthcare site such as Chailey Heritage Marine Hospital, 1.8 miles west of Seaford, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
