How we handle facade sealing in Lancing

External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits. We plan for that and keep you updated. We work on perimeter joints where frames meet the structure, coping and flashing joints and shopfront frames, and the failures we’re asked to look at most are old perimeter mastic that has dried out and gaps between rainscreen or cladding panels. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Lancing it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

For a contractor on a smaller site near Lancing, one mastic visit at the right stage saves return trips. Let us know the key stages and we’ll time the work so nothing waits on us.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

After the work

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Keep pressure washers away from fresh sealant
  • Walk the elevations once or twice a year
  • Plan facade sealing alongside redecoration
  • Check that rainwater leaves the facade the way it was designed to

Record the sealant type and date on the building file. It helps when matching repairs or planning the next reseal without guesswork.

Check older buildings for asbestos before disturbing old mastic. Older sealants can contain asbestos.

Signs you need facade sealing in Lancing

Sun, rain and temperature swings wear facade sealant down over the years. The bead hardens, chalks on the surface and loses the flexibility to follow the joint, and cracks or adhesion loss follow.

Any of the following is a good reason to get the joints checked over:

  • Perimeter sealant that has split or peeled away
  • Air leaks through failed facade joints
  • Leaks at window and door perimeters
  • Weathered joints at frame-to-structure perimeters

When units on a site such as Lancing Business Park, 0.7 miles south-west of Lancing, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Choosing a commercial sealant contractor

Diagnose, treat, sign off

Site rules come first: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Several jobs near Lancing can be grouped on one trip. Mention the building’s opening times and we will work within them.

  1. We start with photos, drawings or a visit to see the joints and agree access.
  2. Product choice follows the joint’s movement and substrate.
  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.

What we need from you

  • Tell staff and tenants when we’ll be in
  • Move anything stored against the joints
  • Share the asbestos register for older buildings

Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Why it’s worth doing now in Lancing

Each spell of rain drives water past a failed facade joint. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing now costs less than repairing interiors later. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.

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 and we’ll price your job on its own details.

Why us?

  • One number for every site we cover
  • 12-month guarantee on workmanship
  • Joints cleaned back to sound surfaces
  • Fully insured

Honest limits

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:

  • Damp caused by condensation inside the building
  • Movement beyond what any sealant can handle
  • Damaged frames that need replacing

If you’re not sure, just call the office on 01277 525 020 or send details through our quote form and we’ll give you a straight answer.

Joints and surfaces we work on

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

How the quote is worked out

Quotes vary with the job. It mainly depends on:

  • How much existing material needs removing
  • The product specified
  • Any access equipment needed
  • How much there is to seal

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

What to include in your enquiry

To price the job accurately, we need to understand the site. Send us:

  • The postcode of the building
  • Photos of the joints, close up and from further back
  • Rough lengths or quantities, or drawings if you have them
  • When you need the work done

Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, call the office on 01277 525 020 or email the details over.

Your questions answered

Is a smaller place like Lancing outside your area?

No. Places such as Lancing are covered as much as the big towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Can being near the sea in Lancing affect the sealant we need?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We check the specified product suits the exposure and pay close attention to preparation.

Can one quote cover more than one building?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

How long does a typical visit take?

It depends on the scope, but the work normally takes anything from a single day to several weeks, depending on joint lengths, access and the weather. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

Do we need an asbestos check before resealing?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. The dutyholder’s asbestos register should be checked first. We don’t remove asbestos-containing materials.

Do you hold CHAS accreditation?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member.

Will you just go over the old 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.

Facade sealing in Lancing: the local picture

With the shore within about 1 mile, Lancing 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, so joint design, primers and product choice deserve extra care. Rainfall across the South East, Lancing 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.

School extensions, at buildings such as The Globe Primary Academy, normally run to the summer holidays, mastic included. For a contractor at a hotel such as Beach Green Hotel (0.5 miles south of Lancing), the mastic often has to be finished before a reopening date.
