Facade sealing in Crondall
Water ingress at window frames is a frequent reason facilities managers contact us. Failed perimeter sealant is a frequent cause. We’ll tell you if we think the leak is coming from somewhere sealant won’t fix. Site teams most often ask us about old perimeter mastic that has dried out and new sealant peeling off old mastic, across cladding panel joints, coping and flashing joints and window and door perimeters. Most enquiries from Crondall start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Construction in and around smaller places such as Crondall is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

What sealant work can’t fix
Being straight saves everyone time. Fresh joints won’t solve:
- Work on the window or framing system itself
- Arranging specialist high-level access, which is planned with the client
- Movement beyond what any sealant can handle
If in doubt, call the office on 01277 525 020 or use the quote form and we will say what we think.
Joints and surfaces we work on
- Perimeter joints where frames meet the structure
- Window and door perimeters
- Shopfront frames
- Stone and brick facade joints
- Coping and flashing joints
- Cladding panel joints
What we’re called out for in Crondall
New sealant run over old sealant rarely holds. Fresh silicone won’t stick to cured silicone, and the patch soon lifts.
Clients usually get in touch after noticing one or more of the following:
- Perimeter sealant that has split or peeled away
- New sealant peeling off old mastic
- Discoloured or dirty facade joints
- Weathered joints at frame-to-structure perimeters
Projects at schools like Crondall Primary School work to term dates, so mastic is programmed tightly.
Before you book anyone
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Will RAMS and insurance details be available?
- Are they CHAS accredited or on Constructionline?
- Proof of insurance

Leave it or put it right?
Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Water through a failed joint rarely stays where it starts. For buildings around smaller places like Crondall, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Our process
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 any cutting starts, and the work usually takes a day or two for a few elevations, and longer where access has to be moved around the building. Smaller jobs around Crondall can be grouped with others nearby. A fixed quote is given before anything starts.
- Photos, drawings or a visit tell us about the joints and the access.
- We confirm the joint type, movement and the specified product.
- Failed beads are removed in full.
- Primer is applied where the maker specifies it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- We go over the completed work with you before leaving.
What we need from you
- Have the specification and drawings to hand
- Clear stock, furniture or equipment away from the joints
- Flag any permit to work we’ll need

Common questions from Crondall clients
Will you take on work at estates like Fleet Business Park, close to Crondall?
Yes. Estates, retail parks and business parks around Crondall, Fleet Business Park among them, are all within reach. To start, just ring 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
Can you take on a job at a hospital such as Spire Clare Park Hospital?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
What type of sealant goes on window perimeters?
The product follows the joint’s movement, the surfaces and the specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing and we follow the specified product.
Can you look at water coming in around a frame?
Yes. Photos help, and you can give us a call on 01277 525 020 or email us to arrange a visit. Many frame leaks are sealant failures, though not all, and we’ll tell you which.
Do you seal on top of existing sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Is Crondall in your area?
Yes. We cover Crondall, within our coverage of Greater London, South East England and Scotland. For a quote, give us a call on 01277 525 020 or email us.
How long does a typical visit take?
That varies with the scale of the job, though a typical visit typically takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Facade sealing around Crondall: how the place shapes the job
Crondall sits in one of the drier corners of the country, the South East. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team. Central London is about 38 miles from Crondall. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes.
Historic houses such as Farnham Castle (to the east of Crondall) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. Units on estates such as Fleet Business Park, 2.2 miles to the north-east of Crondall, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

How the job changes by surface
Window and door perimeters
Aluminium, PVC-U and timber frames each have their own preparation needs. Primer goes on where the manufacturer specifies it for that substrate.
Coping and flashing joints
Coping and flashing joints are included where sealant is the specified fix. They sit in the most exposed positions on the building.
