Facade sealing around Hundred Acres: points for this area
Rainfall across the South East, Hundred Acres included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team. Central London is about 62 miles from Hundred Acres. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme.
On a healthcare site such as Knowle Hospital, 2.4 miles south-west of Hundred Acres, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. Hotels like The Old House Hotel (1.3 miles west of Hundred Acres) rarely close for long, so refurbishment mastic is phased floor by floor.

Common questions from Hundred Acres clients
Will you take on work at estates like Knowle Village Business Park, close to Hundred Acres?
Yes. Our area takes in Hundred Acres and its surroundings, with estates and business parks such as Knowle Village Business Park included. To start, just call 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Do you take on work at healthcare sites like Knowle Hospital?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Can you work in cold or wet weather?
Wet joints or temperatures outside the product’s range mean waiting. The programme allows for it and we tell you if the forecast changes things throughout the job.
Are you CHAS accredited and on Constructionline?
Yes. We’re CHAS accredited and a Constructionline member.
How long do sealant joints last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Should maintenance staff do it?
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Diagnose, treat, sign off
When we get to site, 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 a day or two for a few elevations, and longer where access has to be moved around the building. For work around Hundred Acres, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.
- We plan access and the order of elevations with the client.
- We only seal when joints are dry and within the product’s temperature range.
- Each joint is cut out and the edges inspected.
- 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.
What we need from you
- Point out parking and an unloading spot
- Let building users know which areas are affected
- Point out any areas we must not close

Aftercare for building managers
A few simple habits keep the new joints working:
- Inspect facade joints on a regular cycle
- Confirm the survey covers external sealants in older buildings
- Report water ingress at frames as soon as it shows
- Keep pressure washers away from fresh sealant
Look at perimeter and panel joints as part of routine building checks. Watch for splits, gaps at the edges, hardening and discolouration; record the locations.
Coordinate facade sealing with other external works. Sharing the access keeps the cost down.
What happens if it’s left?
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, saving a second set-up. One visit to deal with every failing joint makes more sense than several trips to a place like Hundred Acres, rather than one at a time. Send photographs of each area and we will quote for the lot.
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

What else we do in Hundred Acres
How the job changes by surface
Brick and stone facades
Brick and stone facades have perimeter and movement joints that need a compatible sealant. Neutral-cure products are used because acetoxy types can mark some stone, with primer where its maker specifies.
Coping and flashing joints
Where the specification calls for sealant at copings or flashings, we can seal them. These joints take full exposure to weather.
Do you need facade sealing in Hundred Acres?
A frequent fault is a bead stuck to the joint’s rear face as well as its sides. With no backing, the sealant is restrained.
If one of these sounds familiar, it’s time for a closer look:
- Draughts around frames and panels
- Gaps between rainscreen or cladding panels
- Facade joints cracked through the middle
- Hard, chalky sealant that no longer flexes
When units on a site such as Knowle Village Business Park (to the south-west of Hundred Acres) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
