Facade sealing in Emsworth, done properly
Some clients need every window on a block resealed; others need a few leaking frames sorted. Either way, the method is the same: old sealant out, faces cleaned, depth set and a new bead tooled in. Each job carries our 12-month guarantee. We work on cladding panel joints, stone and brick facade joints and perimeter joints where frames meet the structure, and the usual reasons a site gets in touch are new sealant peeling off old mastic and weathered facade joints that have lost their grip. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Emsworth, preparation and product choice get the time they need.
In a smaller place such as Emsworth, construction tends to mean small housing schemes, conversions and extensions to community buildings. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

What the job involves on each surface
Brick and stone facades
Joints in natural stone need care to avoid staining. We use a product suitable for the stone where the specification names one, with masked edges for a clean line.
Window and door perimeters
Frames grow and shrink with temperature, and the perimeter joint has to follow. Rod placed at the right depth lets the bead stretch as the frame moves.
FAQs: Emsworth
Is a hospital such as Spire Hospital Portsmouth somewhere you can work?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Does a coastal location like Emsworth affect which sealant is used?
It can. Coastal exposure works external joints harder than inland weather. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Is colour matching possible?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.
How do we ask for a quote?
You can use the quote form on this site; alternatively, call 01277 525 020 or email drawings and photos. Photos, drawings or a joint schedule help us quote quickly.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Do you provide access for facade work?
Access is planned with you before we quote. Tell us about access: existing scaffold, what you are arranging and any site restrictions, and the quote will reflect it.
How do you choose the sealant?
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.
How a job runs
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and our waste is bagged and taken away as we go. Several jobs near Emsworth can be grouped on one trip. Tell us your site hours and we’ll plan around them.
- First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
- The old bead is cut away completely, not overlaid.
- Both faces are cleaned and, where the product needs it, primed.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- The completed runs are checked with you, then the 12-month guarantee applies.
Getting the site ready
- Confirm the product named in the specification
- Arrange parking or a loading space
- Share your working hours and any access restrictions
Getting a fixed quote

Why act early in Emsworth
If access is already up for other work, resealing at the same time makes sense. Coordinating facade sealing with other external works avoids paying for access twice. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Facades, frames and programmes in Emsworth
Emsworth is within about 1 mile of the coast. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, so we check the specified product suits the exposure before the first bead. Several hotels sit less than 2 miles from Emsworth. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
Extensions at sites like Spire Hospital Portsmouth, 1.4 miles to the north-west of Emsworth, usually sit beside working departments, and the mastic follows strict access rules. Historic houses such as Warblington Castle, 1.3 miles to the west of Emsworth, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

Other services in Emsworth
Do you need facade sealing in Emsworth?
Sometimes the substrate is the problem: if the edge of the render, concrete or coating breaks away, the bead goes with it. When the joint edges need repair first, we say so.
It’s worth sending us details if you spot any of the following:
- Previous reseals run over old sealant
- Water coming in around window frames
- Weathered facade joints that have lost their grip
- Perimeter joints where frames meet the structure
When a school such as St James Church of England Controlled Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.
What your quote should include
- Their public liability cover
- Whether old or failed sealant will be cut out, not overlaid
- How long is the guarantee, and what does it include?
- How they handle RAMS and site documents
When it isn’t the sealant
We check first that sealant really is the fix. It won’t put right:
- Water getting in through cracked render or porous masonry
- Movement beyond what any sealant can handle
- Cracked or spalling substrates that need repair before sealing
If in doubt, call the office on 01277 525 020 or send photos by email and we’ll say what we think before you book.

Keeping the joints sound
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Inspect facade joints on a regular cycle
- Clear debris that holds water against joints
- Brief window cleaners about newly sealed joints
- Record the product and colour used on each elevation
Blocked sills and gutters push water at the joints. Good drainage keeps water moving off the facade instead of soaking the joints.
Coordinate facade sealing with other external works. One set-up for several trades saves money.
