Facade sealing for Exton sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Cost factors for facade joints
We price every job individually. The main factors are:
- Travel to remote or island sites
- The size and state of each joint
- The site’s rules and procedures
- The total length or number of joints
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
Sending details for a quote
The more we know, the firmer the quote. Helpful details to send:
- Specification clauses that apply
- The postcode of the building
- What the building is and how it’s used
- The asbestos register, for older buildings
Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. To get it moving, give us a call on 01277 525 020 or email drawings and photos.
Facade sealing in Exton
Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure for clients around Exton. Where sealant is the specified fix, we also take on coping and flashing joints. If you are dealing with water coming in around window frames and unsightly perimeter sealant on a visible elevation, we can help. A single leaking joint is often how a building in Exton first comes to us: we look at the rest while we’re there and tell you what we find.
Around smaller places like Exton, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

When to bring in a specialist
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Building and refurbishing in Exton
The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager. Central London is about 57 miles from Exton. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme.
School extensions, at buildings such as Meonstoke Church of England Infant School, typically run to the summer holidays, mastic included.
Exton is about 7 miles north-west of Horndean, in Hampshire.

What happens if it’s left?
Patch repairs over old sealant tend to come back. A full cut-out and fresh bead is the repair that holds and avoids repeat call-outs. Converted and older buildings near places like Exton tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

From enquiry to sign-off
We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Smaller jobs around Exton can be grouped with others nearby. A fixed quote is given before anything starts.
- We look at the joints, the drawings and the access before pricing.
- The old bead is cut away completely, not overlaid.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- 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.
Before we start on site
- Tell staff and tenants when we’ll be in

Exton: questions and answers
Is Exton too far out for you?
Not at all. Exton is within our area. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
Can you work to our programme on a site in or near Exton?
Yes. The mastic is planned around your key stages. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Do you take on multi-site work?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
How much does the work cost?
Each job is quoted on its own details. To get one, phone 01277 525 020 or email a schedule or drawings.
Can you work while the building is occupied?
Typically, yes. We phase the work so most of the building stays in use.
Does weather matter for sealant work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
What hours do you work?
Give us your site hours and any access windows in your enquiry, and we’ll schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
What we’re called out for in Exton
New sealant run over old sealant rarely holds. Cured silicone won’t accept a new silicone bead.
Things that typically lead to an enquiry:
- Sealant pulling away from frames or panels
- Unsightly perimeter sealant on a visible elevation
- Cold air coming in at window perimeters
- Damp patches beside frames after rain
Older buildings in the area around Exton, such as Hinton Ampner House, which lies north of Exton, need care when sealed: the product has to suit soft or historic materials.

What the job involves on each surface
Precast concrete panels
Precast arrises sometimes crumble or carry old residue. Faces are cleaned to sound concrete, and damaged edges are reported first.
Cladding panel joints
Joints between cladding panels open and close with temperature. The sealant has to match the movement and the panel finish, often a low-modulus silicone or hybrid.
