FAQs: Netherne on-the-Hill
Can you work on a hospital site such as North Downs Hospital?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Can you work at a site such as Ullswater Industrial Estate, by Netherne on-the-Hill?
Yes. Our area takes in Netherne on-the-Hill and its surroundings, with estates and business parks such as Ullswater Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.
Are you insured?

Do you replace windows or glass?

Can you look at water coming in around a frame?

Facade sealing for commercial buildings in Netherne on-the-Hill
A good facade joint depends on design as much as product. The width has to suit the expected movement and the sealant’s movement capability, while rod fixes the depth and stops the bead sticking to the rear, often at around 2:1 width to depth, as the manufacturer advises. The enquiries we see most involve staining on stone next to old sealant and cladding panel joints that have opened up, across stone and brick facade joints, perimeter joints where frames meet the structure and coping and flashing joints. One point of contact handles commercial sealant work in Netherne on-the-Hill from the first photographs to the final walk-round, whether it’s one building or several.
Sites around smaller places like Netherne on-the-Hill can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Send drawings or photographs and the programme and we will quote to suit.
The 12-month guarantee is for workmanship rather than 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.

Related advice
Different surfaces, different methods
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.
Precast concrete panels
Precast panel joints have to absorb thermal and structural movement. We use a sealant with the right movement capability, set over backing rod with primer where the product requires it.
Cost factors for facade joints
The price varies from site to site. It mainly depends on:
- Removal of failed or old sealant
- How accessible the joints are
- Specialist products, such as fire-rated or hygienic sealants
- The size and state of each joint
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 and we’ll explain how it’s made up.
Sending details for a quote
Diagnosis starts before we arrive. Tell us:
- The postcode of the building
- Specification clauses that apply
- Approximate linear metres or a joint schedule
- Photos of the joints, close up and from further back
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, phone 01277 525 020 or email drawings and photos.
Facade sealing around Netherne on-the-Hill: how the place shapes the job
Central London is about 14 miles from Netherne on-the-Hill. 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. Netherne on-the-Hill is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team.
When a college such as Coulsdon Sixth Form College, 1.3 miles north-east of Netherne on-the-Hill, builds or refurbishes, the mastic package normally has to fit around students and staff. New wings at hospitals like North Downs Hospital, 3 miles to the south-east of Netherne on-the-Hill, bring long runs of window and panel joints to seal. Projects at schools like Coulsdon Sixth Form College work to term dates, so mastic is programmed tightly.

What else we do in Netherne on-the-Hill
When it isn’t the sealant
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Arranging specialist high-level access, which is planned with the client
- Damp caused by condensation inside the building
- Replacing glass or failed glazing units
Not sure which it is? You can speak to us on 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.
What we seal
- Coping and flashing joints
- Stone and brick facade joints
- Window and door perimeters
- Shopfront frames
- Perimeter joints where frames meet the structure
- Cladding panel joints
After the work
Your facilities or cleaning team can help the joints last. Share these points with them:
- Note when each elevation was last resealed
- Check the asbestos register before old mastic is disturbed
- Add perimeter sealant to planned maintenance checks
- Combine resealing with other works that need access
Hold back any cleaning crew until the joints have had their stated cure time. Pressure washers and harsh cleaners can damage a fresh bead and tell your cleaning contractor.
Get the joint design right when resealing: correct depth, proper backing and a sealant that can take the movement. Repeating a faulty detail just repeats the failure.
Why it’s worth doing now in Netherne on-the-Hill
A few metres of new sealant compare well with replacing ceilings, linings or damaged stock. Water through a failed joint rarely stays where it starts. Older rural buildings around Netherne on-the-Hill move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
