Facade sealing near Coalhill

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

How the quote is worked out

Quotes vary with the job. Expect it to depend on:

  • How much there is to seal
  • Induction, permit and paperwork requirements
  • Whether old sealant has to be cut out first
  • How accessible the joints are

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Before you send an enquiry

Diagnosis starts before we arrive. Tell us:

  • When you need the work done
  • Clear photographs of the problem areas
  • Specification clauses that apply
  • How the joints are reached, and at what height

Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. The easiest way is to speak to us on 01277 525 020 or send photos by email.

Facade sealing in Coalhill, done properly

Water ingress at window frames is a frequent reason facilities managers contact us. Very often the perimeter bead has cracked or lost its grip. If the evidence points away from the sealant, we say so before quoting. If you’re dealing with weathered joints at frame-to-structure perimeters and air leaks through failed facade joints, we can put it right. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Coalhill, that means joint design, primers and backing rod as standard.

Around smaller places like Coalhill, building work usually means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Questions we’re asked in Coalhill

Does your area include sites such as Western Industrial Estate, near Coalhill?

Yes. Estates, retail parks and business parks around Coalhill, Western Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.

Is a smaller place like Coalhill outside your area?

Not at all. Coalhill is within our area. London and every South East county are within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Do you replace windows or glass?

No. A glazing contractor handles that. We reseal window perimeters, panel joints and frame-to-structure perimeters on commercial buildings.

Can you work in cold or wet weather?

Wet joints or temperatures outside the product’s range mean waiting. We plan for weather and keep you updated as the work goes on.

Can you quote from photos?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.

Do you provide access for facade work?

We agree access with the client at the start. Let us know what access is in place or planned, and the quote will reflect it.

Can you find out why a window is leaking?

Yes. We look at the perimeter sealant and tell you whether it has failed as part of pricing. If the water seems to come from a roof, sill or the glazing unit instead, we say so.

On site: what to expect

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes a day or two for a few elevations, and longer where access has to be moved around the building, and we clear our waste as we work. Jobs in and around smaller places like Coalhill are usually planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. We plan access and the order of elevations with the client.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. Each joint is cut out and the edges inspected.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. We hand over with our 12-month workmanship guarantee.

Getting the site ready

  • Send any specification or drawings in advance
  • Let us know about inductions and permits
  • Clear stock, furniture or equipment away from the joints

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.

When it isn’t the sealant

Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:

  • Cracked or spalling substrates that need repair before sealing
  • Arranging specialist high-level access, which is planned with the client
  • Replacing glass or failed glazing units

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

Surfaces we seal

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

Should maintenance staff do it?

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

What the job involves on each surface

Brick and stone facades

On masonry, the sealant has to suit a porous, textured surface. Neutral-cure products are used because acetoxy types can mark some stone.

Coping and flashing joints

Sometimes the coping or flashing itself has failed. Where the issue isn’t the sealant, we say so.

Common problems we fix in Coalhill

Not every failure is in the sealant: if the edge of the render, concrete or coating breaks away, the bead goes with it. When the joint edges need repair first, we say so.

It’s worth sending us details if you spot any of the following:

  • Weathered facade joints that have lost their grip
  • Leaks at window and door perimeters
  • Patch repairs that keep failing
  • Discoloured or dirty facade joints

Recladding or extending a unit at a site like Western Industrial Estate, 2.9 miles to the east of Coalhill, brings panel joints and frame perimeters into the programme.

Before you book anyone

  • How the joint faces will be prepared and primed
  • Can the work be phased to keep areas open?
  • What the guarantee covers, and for how long
  • Which product they’ll use, and why it suits the joint
