Our process
Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. What matters most for a job in Denmead is a clear list of what needs doing. A fixed quote follows.
- We look at the joints, the drawings and the access before pricing.
- 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.
- The new sealant goes in and is tooled firmly onto both faces.
- The completed runs are checked with you, then the 12-month guarantee applies.
What we need from you
- Share the asbestos register for older buildings
- Tell staff and tenants when we will be in
- Tell us your opening times and when work is allowed

Facade sealing in Denmead
Facade sealants sit in the sun, rain and frost every day, and they wear out over time. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When it fails, the whole bead is cut away and the joint rebuilt. Most enquiries involve weathered joints at frame-to-structure perimeters and discoloured or dirty facade joints, across shopfront frames, perimeter joints where frames meet the structure and cladding panel joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Denmead, preparation and product choice get the time they need.
On a small site around Denmead, the mastic is best done in the fewest visits we can manage. Let us know the key stages and we’ll time the work so nothing waits on us.
Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

New build and refits around Denmead
Denmead is in the South East, one of the UK’s drier regions. 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. Denmead is about 59 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, so mastic packages have to keep pace with busy programmes.
Hospital estates such as Queen Alexandra Hospital, 3.5 miles to the south of Denmead, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. Units on estates such as Parklands Business Park (under half a mile south of Denmead) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
Denmead is about 2 miles north-west of Waterlooville, in Hampshire. Our applicators travel to Denmead for work on facade joints. Our Hampshire coverage takes in 723 places, from busy centres to rural villages. Portsmouth is covered too, some 6 miles away.

What the job involves on each surface
Cladding panel joints
Joints between cladding panels open and close with temperature. The sealant has to match the movement and the panel finish.
Coping and flashing joints
Not every coping or flashing leak is a sealant problem. We tell you if the fix is a roofing or metalwork job rather than a reseal.
Site staff or a sealant specialist?
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.
When it isn’t the sealant
Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:
- Specialist high-level access methods
- Damp caused by condensation inside the building
- Work on the window or framing system itself
If you are not sure, just ring 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.

Denmead: questions and answers
Do you cover business parks and estates near Denmead, such as Parklands Business Park?
Yes. We cover Denmead and the area around it, including industrial estates, business parks and retail parks such as Parklands Business Park. Photos and a short description are enough for a first look.
Is Denmead too small for you to travel to?
Not at all. Denmead is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Can you just add new sealant on top?
No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the faces are cleaned before resealing. Nothing else gives a bond that lasts.
Should we check old sealant for asbestos?
For older buildings, yes, check before work starts. The dutyholder holds the asbestos register, so ask for it before we start. Suspect material is left alone until it has been tested.
Can you work while the building is occupied?
Usually, yes. We phase the work so most of the building stays in use, with each area protected and signed.
Do your applicators hold CSCS cards?
Yes. Our applicators hold CSCS cards, as many construction sites ask for.
Will you check whether the sealant is causing the leak?
Yes. Photos help, and you can speak to us on 01277 525 020 or email us to arrange a visit. Failed perimeter sealant is a common cause, but not the only one.
Leave it or put it right?
The longer a failed joint is left, the more the substrate suffers: wet edges break down, so repairs may be needed before resealing. Acting at the first sign of splitting keeps the fix simple. Small buildings around Denmead suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Signs you need facade sealing in Denmead
When sealant lets go of a frame or panel, the cause is often the preparation. Dust, old sealant residue, damp or a missing primer stop it bonding properly, and the joint opens with the first real movement.
Things that typically lead to an enquiry:
- Perimeter joints where frames meet the structure
- Patch repairs that keep failing
- Air leaks through failed facade joints
- Hard, chalky sealant that no longer flexes
Projects at schools like Denmead Junior School work to term dates, so mastic is programmed tightly.
What your quote should include
- Their public liability cover
- Which product they’ll use, and why it suits the joint
- Their approach to joint depth and backing
- Whether old or failed sealant will be cut out, not overlaid
