Common questions from Sandown clients
Our building in Sandown is near the coast: does that change the sealant?
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 Sandown too far out for you?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.
Will your applicators have CSCS cards?
Yes. If you need card details for site access, let us know and we’ll send them with the quote.
When can the area be used after sealing?
We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Do you provide access for facade work?
That comes down to the access arranged for the job. Share what access exists or is planned when you send details, and we’ll plan the work with you.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Are you CHAS accredited?
Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.
Facade sealing in Sandown, done properly
Some clients need every window on a block resealed; others need a few leaking frames sorted. The approach doesn’t change with the size: cut out, clean, back, prime where needed and seal. Each job carries our 12-month guarantee. Most enquiries involve new sealant peeling off old mastic and old perimeter mastic that has dried out, on coping and flashing joints, window and door perimeters and perimeter joints where frames meet the structure. Whoever orders the work in Sandown, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Conversions around smaller places like Sandown often join new frames to old masonry or timber, and the sealant at those junctions has to cope with two materials that move differently.
Work we carry out in the Isle of Wight comes with a 12-month guarantee. If an installation problem shows up, give us a call on 01277 525 020 or email a schedule or drawings and we’ll arrange a return visit.

Common problems we fix in Sandown
Not every failure is in the sealant: crumbling render, spalling concrete or flaking paint take the sealant with them. We tell you when the edges need repairing before resealing.
Things that normally lead to an enquiry:
- Weathered joints at frame-to-structure perimeters
- Sealant pulling away from frames or panels
- Hard, chalky sealant that no longer flexes
- Cold air coming in at window perimeters
Extensions at sites like Arthur Webster Memorial Hospital for Children, 1.6 miles south-west of Sandown, typically sit beside working departments, and the mastic follows strict access rules.
Questions to ask before you book
- How joint depth will be controlled
- How they handle RAMS and site documents
- How they’ll work around occupants
- Do they follow the manufacturer’s priming guidance?
Why it’s worth doing now in Sandown
Every shower drives water through a split perimeter bead. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing early costs far less than repairing what the water reaches. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.
Why appoint us
- Fixed quotes based on photos, drawings or a visit
- Health and safety: CHAS accredited
- Coloured sealants to suit the setting, where available
- Specification-led, product-correct work
Take a look at what affects the cost and how we’re accredited.
What the job involves on each surface
Window and door perimeters
Frame-to-wall joints at windows and doors are the facade joints we reseal most. A low-modulus, neutral-cure product suits most frame-to-wall joints.
Perimeter joints at frames and structure
These frame-to-structure joints take a lot of movement and weather. We cut them out, prepare both faces and reseal to the specification using a sealant classified for that use.

What else we do in Sandown
What we can’t put right
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:
- Replacing glass or failed glazing units
- Render or concrete edges that have broken away
- Arranging specialist high-level access, which is planned with the client
Not sure which it is? You can speak to us on 01277 525 020 or email the details over and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Cladding panel joints
- Perimeter joints where frames meet the structure
- Shopfront frames
- Window and door perimeters
- Coping and flashing joints
- Stone and brick facade joints
After the work
Problems stay small when the joints are checked regularly. In particular:
- Add perimeter sealant to planned maintenance checks
- Confirm the survey covers external sealants in older buildings
- Report water ingress at frames as soon as it shows
- Clear debris that holds water against joints
Following storms, look inside for damp or staining near frames. An early report normally means a small reseal rather than a bigger repair.
Don’t wait for a full elevation to fail. Small repairs stop small leaks becoming large ones inside the building.
Sites and facades in and around Sandown
The sea is no more than about 1 mile from Sandown. Coastal exposure means perimeter and cladding joints work harder than on an inland job, and the sealant, primer and backing need choosing with that in mind. Rainfall across the South East, Sandown included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager.
Older buildings in the area around Sandown, such as Morton Manor, which lies north-east of Sandown, need care when sealed: the product has to suit soft or historic materials. Work at a hotel such as Chad Hill Hotel (under half a mile north-east of Sandown) tends to be programmed around bookings, mastic included.

Our process
On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself normally taking anything from a single day to several weeks, depending on joint lengths, access and the weather. If neighbouring businesses or buildings around Sandown need work too, visits can be combined. Tell us your site hours and we’ll plan around them.
- We plan access and the order of elevations with the client.
- Weather and temperature are checked against the product’s limits.
- We remove the old bead and check the edges are sound.
- Joints are cleaned, primed if required and fitted with backing rod.
- Facade-grade sealant goes in and is tooled to a tidy concave profile.
- Once signed off, the work carries our 12-month guarantee.
Before we start on site
- Tell us your opening times and when work is allowed
- Point out any areas we must not close
- Make sure the joints can be reached
