Facade sealing for businesses in Selsfield Common

About our facade sealing in Selsfield Common

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. If you’re dealing with weathered joints at frame-to-structure perimeters and failed sealant on precast panel joints, we can help. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Selsfield Common, preparation and product choice get the time they need.

In the countryside around places like Selsfield Common, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, give us a call on 01277 525 020 or send photos by email and we’ll arrange a return visit.

From enquiry to sign-off

Before we leave any area, we remove the tape, clean down and inspect every joint, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. If others near Selsfield Common need work, visits can be combined. A fixed quote is given before anything starts.

  1. First we review photographs, 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. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. We walk the finished joints with you before handing over.

Getting the site ready

Advice

Your questions answered

Can you take on a job at a hospital such as Queen Victoria Hospital?

Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.

Is Selsfield Common too far out for you?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.

What hours do you work?

We’re in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.

Do you guarantee your work?

Yes. Our workmanship is backed for 12 months.

How do we ask for a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.

Are you CHAS accredited?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.

Is old mastic on our building likely to contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. The dutyholder’s asbestos register should be checked first; if it’s suspected, work stops until it has been tested. Removal of asbestos isn’t something we do.

How the job changes by surface

Perimeter joints at frames and structure

These frame-to-structure joints take a lot of movement and weather. We cut them out, prepare both faces and reseal to the specification.

Coping and flashing joints

Where the specification calls for sealant at copings or flashings, we can seal them. They sit in the most exposed positions on the building and need a durable external sealant.

Common problems we fix in Selsfield Common

When the sealant tears down its centre, it has usually been asked to move more than it can. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.

Clients typically get in touch after noticing something like this:

  • Perimeter sealant that has split or peeled away
  • Discoloured or dirty facade joints
  • Failed seals around shopfront and entrance frames
  • Cladding panel joints that have opened up

Older buildings in the area around Selsfield Common, such as Gravetye Manor, 0.8 miles to the east of Selsfield Common, need care when sealed: the product has to suit soft or historic materials.

What your quote should include

  • Their public liability cover
  • Whether primer will be used where the manufacturer specifies it
  • Their plan for phasing and protecting the area
  • What the guarantee covers, and for how long

Our contractor checklist

When it isn’t the sealant

Sealant solves a lot, but not everything, and we are upfront when that’s the case. These need a different solution:

  • Damp caused by condensation inside the building
  • Render or concrete edges that have broken away
  • Installing or repairing glazing systems

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

Joints and surfaces we work on

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

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 existing material needs removing
  • Which sealant the job calls for
  • Site requirements such as inductions and permits
  • Location, for remote and island sites

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Sending details for a quote

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

  • Photos of the joints, close up and from further back
  • The postcode of the building
  • How the joints are reached, and at what height
  • Approximate linear metres or a joint schedule

To get a fixed quote, give us a call on 01277 525 020 or email drawings and photos with the site address and an outline of the work. You can also send details through our quote form.

Leave it or put it right?

Patch repairs over old sealant tend to come back. A full cut-out and fresh bead is the repair that holds. Around Selsfield Common, it’s better to renew all the failing joints at once. Send photos of each area and we’ll quote for the lot.

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

  • Work carried out by CSCS-carded applicators
  • A Constructionline member, so easy to vet

Facades, frames and programmes in Selsfield Common

Selsfield Common has several hotels close by, all within 2 miles. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. Central London is about 28 miles from Selsfield Common. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme.

For contractors at a school such as Turners Hill CofE Primary School, sealing has to be finished before term starts. Hotel extensions and refits, at places such as Alexander House Hotel & Utopia Spa (1.1 miles north of Selsfield Common), typically run between busy periods, so the sealing is squeezed into short windows.
