Facade sealing in Martin

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Facade sealing for commercial buildings in Martin

Sealant around windows, doors and cladding panels stops rain reaching the wall behind. Once a perimeter seal fails, water tracks in around frames and panels. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. If you are dealing with staining on stone next to old sealant and previous reseals run over old sealant, we can put it right, on window and door perimeters, cladding panel joints and shopfront frames alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Martin is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

For a site near Martin, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Send drawings or photographs and the programme and we will quote to suit.

Every job we finish is backed by a 12-month workmanship guarantee, in Martin as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Common problems we fix in Martin

Most facade joints fail through age and weathering. UV and weather harden the sealant until it can’t stretch with the building, and cracks or adhesion loss follow.

Common reasons buildings call us in:

  • Water coming in around window frames
  • Old perimeter mastic that has dried out
  • Failed sealant on precast panel joints
  • Perimeter sealant that has split or peeled away

For contractors building in or near Martin, we seal to the drawings, the specification and the programme.

Questions to ask before you book

  • Can the work be phased to keep areas open?
  • How the existing material will be dealt with
  • What site paperwork they can supply
  • The terms of the workmanship guarantee

Our contractor checklist

Leave it or put it right?

Open facade joints also let air and dirt through: occupants notice draughts and cold spots around windows. A new seal closes the gap for both. Older rural buildings around Martin move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Questions about Martin

Is Martin too far out for you?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Which documents can you supply for work in Martin?

RAMS, insurance certificate, CSCS details: list what the site needs and we’ll confirm it with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.

Can weather delay the job?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Can you find out why a window is leaking?

Yes. We check the sealant joints and report what we find. If the water seems to come from a roof, sill or the glazing unit instead, we say so.

Do you need to see the site first?

Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.

Are you CHAS accredited?

Yes. We’re CHAS accredited and a Constructionline member.

Do you have public liability insurance?

Yes. We’re fully insured, including public liability cover.

Honest limits

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Joints too narrow for the movement they take, which need redesign
  • Water getting in through cracked render or porous masonry
  • Replacing glass or failed glazing units

Not sure which it is? You can phone 01277 525 020 or send photos by email and we will tell you honestly before you book.

Joints and surfaces we work on

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

Diagnose, treat, sign off

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then handed back before the next one starts. If others near Martin need work, visits can be combined. A fixed quote is given before anything starts.

  1. Access, site rules and timing are settled with the client up front.
  2. Weather and temperature are checked against the product’s limits.
  3. Each joint is cut out and the edges inspected.
  4. Faces are cleaned, primed where needed and backed.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. We hand over with our 12-month workmanship guarantee.

Preparing the site

  • Send asbestos survey details if the building is pre-2000
  • Send any specification or drawings in advance
  • Point out parking and an unloading spot

Martin sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack.

A facade joint near Martin lasts when width, depth and backing are right, not just the finish.

Commercial clients in Martin

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

After the work

Keep the joints in good shape with a few simple steps:

  • Record the product and colour used on each elevation
  • Ask about asbestos in pre-2000 mastic
  • Check that rainwater leaves the facade the way it was designed to
  • Never let anyone seal over old sealant

Include facade joints in your planned maintenance inspections. Signs to look for are cracking, edges lifting, chalking and stiffness; note where they appear.

Building facade joints into a maintenance cycle avoids emergency repairs. Regular checks let you renew joints before water gets in, rather than waiting for a ceiling stain.
