Need facade sealing in Lower Halstow?

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

What sets the cost

A fixed quote reflects the actual work. It takes account of:

  • Travel to remote or island sites
  • Specialist products, such as fire-rated or hygienic sealants
  • Phasing around occupants
  • Backing rod, priming and other preparation

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

What to include in your enquiry

A few photos plus some basic facts will normally do. Please tell us:

  • Whether an asbestos survey exists
  • Where the site is, with the postcode
  • Clear photos of the problem areas
  • Access details, including height

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to call the office on 01277 525 020 or email a schedule or drawings with what you know.

About our facade sealing in Lower Halstow

Installing framed glazing systems isn’t part of our work. What we seal are the joints around them: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds with products suited to facade or glazing perimeter joints. We work on shopfront frames, cladding panel joints and coping and flashing joints, and the usual reasons a site gets in touch are gaps between rainscreen or cladding panels and damp patches beside frames after rain. Facilities teams, main contractors and managing agents in Lower Halstow tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Construction in and around smaller places such as Lower Halstow is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

When something else is needed

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Joints too narrow for the movement they take, which need redesign
  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Replacing glass or failed glazing units

If you are not sure, just phone 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.

Joints and surfaces we work on

  • Coping and flashing joints
  • Stone and brick facade joints
  • Window and door perimeters
  • Perimeter joints where frames meet the structure
  • Cladding panel joints
  • Shopfront frames

Leave it or put it right?

Scaffold or access already on site makes resealing much simpler. Combine it with planned external works and you only arrange access once. Halls, stores and units around places like Lower Halstow may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

A quote for facade joints depends on how many there are, their condition and the access, plus any specification you’re working to. Call for a quote.

Why appoint us

  • Work to your specification and the manufacturer’s guidance
  • 12-month guarantee on workmanship
  • One contact handling all your sites
  • Old sealant cut out, never sealed over

Sites and facades in and around Lower Halstow

With the shore within about 2 miles, Lower Halstow counts as a coastal location. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, and the sealant, primer and backing need choosing with that in mind. Rainfall across the South East, Lower Halstow included, is lower than in many parts of the UK. 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.

Units on estates such as Newington Enterprise Centre (1 mile south of Lower Halstow) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. New wings at hospitals like Medway Maritime Hospital (to the west of Lower Halstow) bring long runs of window and panel joints to seal. Projects at schools like Lower Halstow Primary School work to term dates, so mastic is programmed tightly.

Our process

Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Smaller jobs around Lower Halstow can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. We confirm the joint type, movement and the specified product.
  3. Failed beads are removed in full.
  4. Primer goes on where the product data asks for it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. We go over the completed work with you before leaving.

Getting the site ready

  • For older buildings, check the asbestos register before work
  • Move anything stored against the joints
  • Confirm the product named in the specification

Related advice

General trades versus a specialist

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

FAQs: Lower Halstow

Is hospital work, at somewhere like Medway Maritime Hospital, something you do?

Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.

Do you cover business parks and estates near Lower Halstow, such as Newington Enterprise Centre?

Yes. Estates, retail parks and business parks around Lower Halstow, Newington Enterprise Centre among them, are all within reach. Photos and a short description are enough for a first look.

Will you check whether the sealant is causing the leak?

Yes. We look at the perimeter sealant and tell you whether it has failed as part of pricing. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.

Should we check old sealant for asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Check the asbestos register or survey before it is disturbed. We don’t remove asbestos-containing materials.

Can weather delay the job?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

Is it okay to overlay old mastic?

No. Overlaying is a shortcut that peels away quickly. Our method is a full cut-out, cleaning, backing and a new bead.

What do you charge?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we’ll price it properly.

Different surfaces, different methods

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, primed where the maker specifies.

Render and coated surfaces

Sealant can only hold as well as the render or paint beneath it. Loose coatings are cleaned back first, and areas needing repair are flagged.
