Facade sealing across Ulcombe

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

Diagnose, treat, sign off

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Smaller jobs around Ulcombe can be grouped with others nearby. A fixed quote is given before anything starts.

  1. First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. The old bead is cut away completely, not overlaid.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Getting the site ready

  • Make sure the joints can be reached
  • Share your working hours and any access restrictions
  • Send asbestos survey details if the building is pre-2000

About our facade sealing in Ulcombe

Every facade quote starts with how the joints will be reached. Let us know what access exists or is planned, and any site rules we need to work around, and we’ll fit the work around it. If you are dealing with sealant pulling away from frames or panels and cladding panel joints that have opened up, we can help. Facilities teams, main contractors and managing agents in Ulcombe tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Conversions of older rural buildings near smaller places such as Ulcombe bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

How the quote is worked out

Sealant work doesn’t have a standard rate, because every site is different. What we look at:

  • How much there is to seal
  • Phasing around occupants
  • Joint width, depth and condition
  • The product specified

The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

Details that help us quote

The more we know, the firmer the quote. When you get in touch, include:

  • Drawings or a marked-up plan, if available
  • Photos of the joints, close up and from further back
  • Any specification or named product
  • Where the site is, with the postcode

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, call the office on 01277 525 020 or email drawings and photos.

Ulcombe: questions and answers

Will you take on work at estates like Roebuck Business Park, close to Ulcombe?

Yes. We cover Ulcombe and the area around it, including industrial estates, business parks and retail parks such as Roebuck Business Park. Photos and a short description are enough for a first look.

Can work at a site such as Canterbury Christ Church University fit around teaching?

Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Are you CHAS accredited?

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

What about RAMS and site documents?

Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.

Can you just add new sealant on top?

No. New sealant won’t hold on old sealant, so the old bead is cut away. That is what makes the new joint last.

Which sealant will you use?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Is it fine to apply new sealant on top of old?

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Site staff or a sealant specialist?

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Facade sealing around Ulcombe: how the place shapes the job

Central London is about 37 miles from Ulcombe. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, so mastic packages have to keep pace with busy programmes. The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack.

For contractors at a school such as Ulcombe Church of England Primary School, sealing has to be finished before term starts. New units and refits on sites such as Roebuck Business Park (2.2 miles north-east of Ulcombe) need their panel and perimeter joints sealed to the specification.

Ulcombe is about 6 miles south-east of Maidstone, in Kent. Our applicators travel to Ulcombe for work on facade joints. Our Kent coverage takes in 931 places. There’s a separate page for London, roughly 37 miles from Ulcombe.

If your building is just outside Ulcombe, we cover Fairbourne Heath (1 mile north-east), Eastwood (1 mile south-east), Kingswood (1 mile north-west), Chartway Street (1 mile north-west) and Broadstone (1 mile south-east).

Do you need facade sealing in Ulcombe?

A frequent fault is a bead stuck to the joint’s rear face as well as its sides. Without rod or bond-breaker tape, the bead is held back and rips when the facade moves.

Look out for the following:

  • Sealant pulling away from frames or panels
  • Patch repairs that keep failing
  • Unsightly perimeter sealant on a visible elevation
  • Perimeter joints where frames meet the structure

University estates such as Canterbury Christ Church University (to the north of Ulcombe) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.

Questions to ask before you book

  • Will failed sealant be removed rather than covered?
  • Can the work be phased to keep areas open?
  • Will CSCS-carded applicators be on site?
  • Are they CHAS accredited or on Constructionline?

Questions to ask before you appoint anyone

What sealant work can’t fix

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is one of these:

  • Joints too narrow for the movement they take, which need redesign
  • Replacing glass or failed glazing units
  • Specialist high-level access methods

If you’re not sure, just ring 01277 525 020 or email the details over and we’ll give you a straight answer before you book.

What we seal

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

After the work

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Walk the elevations once or twice a year
  • Avoid harsh cleaners on facade sealant
  • Check the asbestos register before old mastic is disturbed
  • Keep the sealant details on the building file

If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Ask the installer to reseal it properly.

Tie resealing in with redecoration, cladding repairs or other access. One set-up for several trades saves money and limits disruption.
