FAQs: Northdown
Do you take on work at healthcare sites like Queen Elizabeth The Queen Mother Hospital?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is a smaller place like Northdown outside your area?
No. Places such as Northdown are covered as much as the big towns. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
How is access to upper-level joints handled?
Access is planned with you before we quote. Tell us about access: existing scaffold, what you’re arranging and any site restrictions, and we’ll price the work around it.
Can the building stay open while you work?
Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.
Can the sealant be colour-matched?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
Do your applicators hold CSCS cards?
Yes. Should the site need card details in advance, let us know and we will send them with the quote.
Do you take on multi-site work?
Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.
Facade sealing in Northdown
Sealant around windows, doors and cladding panels stops rain reaching the wall behind. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We remove failed sealant and install a new bead chosen for the joint and how far it moves. If you have failed seals around shopfront and entrance frames and water coming in around window frames, we can put it right, on cladding panel joints, shopfront frames and coping and flashing joints alike. Whoever orders the work in Northdown, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.
Building work in places the size of Northdown is normally small-scale: a handful of new houses, barn conversions, a school or hall extension. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant.

When something else is needed
Being straight saves everyone time. Fresh joints won’t solve:

- Damaged frames that need replacing

Facade sealing in Northdown: the local picture
Northdown lies within about 1 mile of the sea. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, so we check the specified product suits the exposure before the first bead. Northdown sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager.
For contractors at a college like TOPS Vocational College, 1.3 miles west of Northdown, perimeters and internal sealant are timed for the holidays. School extensions, at buildings such as Palm Bay Primary School, normally run to the summer holidays, mastic included.
Northdown is about 2 miles east of Margate, in Kent. Our applicators travel to Northdown for work on facade joints. Northdown is one of 931 places we cover in Kent for facade joints. London is covered too, some 66 miles away.
Business premises anywhere in CT9 and CT10 are within our area. If your site is on Old Road, Holly Lane and Green Lane or close by, send details and we’ll quote for facade joints. Just outside Northdown, we also work in Palm Bay (1 mile north-west), Cliftonville (1 mile west), Kingsgate (1 mile east), St Peter's (1 mile south) and Broadstairs (2 miles south). Nearby towns on our patch include Ramsgate (3 miles south), Deal (12 miles south), Herne Bay (12 miles west), Walmer (13 miles south), St Lawrence (3 miles south) and Newington (3 miles south-west).

On site: what to expect
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself normally takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and we clear our waste as we work. If neighbouring businesses or buildings around Northdown need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.
- Photos, drawings or a visit tell us about the joints and the access.
- Product choice follows the joint’s movement and substrate.
- Failed beads are removed in full.
- Primer goes on where the product data asks for it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- The finished joints are checked with you.
What we need from you
- Send any specification or drawings in advance
- Let building users know which areas are affected
- Send asbestos survey details if the building is pre-2000

Advice
What sets the cost
To price the job, we consider:
- Site requirements such as inductions and permits
- Distance, for remote addresses
- Backing rod, priming and other preparation
- Any access equipment needed
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.
Before you send an enquiry
We can often quote from photographs and a few details. Please tell us:
- The type of building and who uses it
- When you need the work done
- The asbestos register, for older buildings
- Any specification or named product
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.
Do you need facade sealing in Northdown?
Not every failure is in the sealant: if the edge of the render, concrete or coating breaks away, the bead goes with it. When the joint edges need repair first, we say so.
It’s worth sending us details if you spot any of the following:
- Facade joints cracked through the middle
- Staining on stone next to old sealant
- Water coming in around window frames
- New sealant peeling off old mastic
For a contractor at a hotel such as Botany Bay Hotel, 0.7 miles to the east of Northdown, the mastic often has to be finished before a reopening date.
What to look for in a quote
- Will failed sealant be removed rather than covered?
- What level of public liability insurance do they hold?
- Are they CHAS accredited or on Constructionline?
- What the guarantee covers, and for how long
Why act early in Northdown
Every shower drives water through a split perimeter bead. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing early costs far less than repairing what the water reaches. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.
Why appoint us
- One contact handling all your sites
- Clear, fixed quotes

- Work carried out by CSCS-carded applicators

Aftercare for building managers
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Avoid patch repairs on failed facade joints
- Add perimeter sealant to planned maintenance checks
- Ask about asbestos in pre-2000 mastic
- Clear debris that holds water against joints
After heavy weather, check vulnerable elevations for signs of water inside. An early report typically means a small reseal rather than a bigger repair.
In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it.
