About our mastic sealing in Seaford
For blocks and buildings in Seaford and across East Sussex, the process is the same: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. A list of buildings, a few photos and approximate joint numbers are enough for a quick quote or we can visit. Most enquiries involve open joints in brickwork or panels and repeated reactive repairs to the same buildings, across shopfronts below residential blocks, balcony and threshold joints and communal entrances and stairwells. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Seaford is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In Seaford, as in most towns, a block may have frames from several eras, so mastic around them can be of mixed age and quality. Looking at the whole building first shows what needs doing now and what can wait.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

When to bring in a specialist
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Maintenance after handover
A few simple habits keep the new joints working:
- Track which buildings were done and when
- Check the asbestos register before any old mastic is disturbed
- Mention RAMS, insurance or CSCS requirements up front
- Check sealant joints during planned building inspections
Where a paintable product was specified, it can be painted after curing. Non-paintable silicone shouldn’t be painted over unless told otherwise.
The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing and the job grows.
For managing agents and facilities managers
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
Diagnose, treat, sign off
When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself normally taking a day or two for a single block, longer for an estate programme. If you have more than one building in Seaford, they can often be done on the same visit, with one quote covering them. Give us your access times and we will fit the work in.
- Each block or building is walked and the failed joints recorded with the likely cause.
- You get a fixed quote, priced per building where that helps your budgeting.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Old sealant is stripped and each face prepared back to firm material.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Before we start on site
- Confirm the product named in the specification
- Arrange parking or a loading space
- Agree which areas must stay open

FAQs: Seaford
Can you work in a care home near Seaford with residents in?
Yes. Care settings are planned area by area, at times agreed with the home. Tell us about any infection-control or safeguarding requirements and we will work to them.
Can being near the sea in Seaford affect the sealant we need?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
When can the area be used after sealing?
We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
Can you quote from photographs?
Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit.
What guarantee do you give on resealing?
There is a 12-month guarantee on our workmanship and we hold public liability insurance.
What about access for upper-floor joints?
Every block is different. How upper joints are reached is agreed before work is booked so the fixed quote reflects it.
Quoting for work in Seaford
Before we quote, we look at:
- The size and state of each joint
- Access and working height
- Whether old sealant has to be cut out first
- Which sealant the job calls for
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
What to include in your enquiry
We can often quote from photos and a few details. It helps to include:
- Specification clauses that apply
- Anything awkward about access or site hours
- Photos of the joints, close up and from further back
- Where the site is, with the postcode
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.
What we can’t put right
Sealant solves a lot, but not everything, and we are upfront when that’s the case. It won’t fix:
- Substrate edges that need repairing first
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Frames that are rotten, warped or broken
If in doubt, phone 01277 525 020 or use the quote form and we will say what we think.
Surfaces we seal
- Window and door perimeters on blocks
- Communal entrances and stairwells
- External wall and movement joints
- Communal kitchens and washrooms
- Shopfronts below residential blocks
- Balcony and threshold joints
