Facade sealing in Lagness, done properly
Installing framed glazing systems isn’t part of our work. What we seal are the joints around them: perimeter joints where frames meet the structure, panel joints and window perimeters, using sealants classified for facade or glazing use. Site teams most often ask us about weathered facade joints that have lost their grip and damp patches beside frames after rain, across window and door perimeters, perimeter joints where frames meet the structure and shopfront frames. Looking for mastic applicators who cover Lagness? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
For a site near Lagness, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Drawings, photos and the programme let us give a fixed quote.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

On site: what to expect
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes a day or two for a few elevations, and longer where access has to be moved around the building, and we clear our waste as we work. Smaller jobs around Lagness can be grouped with others nearby. You’ll have a fixed quote before work starts.
- We plan access and the order of elevations with the client.
- Weather and temperature are checked against the product’s limits.

When to bring in a specialist
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
How the job changes by surface
Perimeter joints at frames and structure
These frame-to-structure joints take a lot of movement and weather. They are cut out, cleaned, backed and resealed using a sealant classified for that use.
Brick and stone facades
Stone can absorb plasticisers from the wrong sealant. The specified stone-compatible sealant is what we use, and mask the edges carefully.
Do you need facade sealing in Lagness?
Three-sided adhesion is a classic installation fault. With no backing, the sealant is restrained and rips when the facade moves.
Most enquiries start with one or more of the following:
- Staining on stone next to old sealant
- Air leaks through failed facade joints
- Previous reseals run over old sealant
- Failed sealant on precast panel joints
Recladding or extending a unit at a site like Quarry Lane Industrial Estate, 2.4 miles to the north-west of Lagness, brings panel joints and frame perimeters into the programme.

Lagness: questions and answers
Does the sea air around Lagness change the choice of sealant?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Can you take on a job at a hospital such as Bognor Regis War Memorial Hospital?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is the work guaranteed?
Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.
What about RAMS and site documents?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Do you offer coloured sealant?
That depends on the product specified. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Sites and facades in and around Lagness
Lagness sits close to the coast, within about 2 miles. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Central London is about 56 miles from Lagness. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, which keeps mastic packages in demand.
On a healthcare site such as Bognor Regis War Memorial Hospital, 2.4 miles east of Lagness, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. When a school such as Rose Green Junior School is extended or refurbished, the mastic package is often squeezed into the holidays.

When it isn’t the sealant
Honesty saves time and money. Fresh joints won’t solve:
- Water getting in through cracked render or porous masonry
