Facade sealing for Chegworth sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Why deal with it now?

Leaving failed perimeter sealant also makes the eventual job bigger: wet edges break down, so repairs may be needed before resealing. Early action keeps it simple. For buildings around smaller places like Chegworth, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Facade sealing for commercial buildings in Chegworth

Managing agents and owners in Chegworth ask us to, we reseal perimeters across whole elevations or a handful of problem windows. Either way, the method is the same: cut out, clean, back, prime where needed and seal. A 12-month guarantee applies to our workmanship. We work on coping and flashing joints, shopfront frames and stone and brick facade joints, and what we’re called in for most is perimeter sealant that has split or peeled away and new sealant peeling off old mastic. Looking for mastic applicators who cover Chegworth? We’ve been sealing commercial buildings since 2005.

For a site near Chegworth, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Send drawings or photos and the programme and we’ll quote to suit.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Honest limits

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Specialist high-level access methods
  • Installing or repairing glazing systems
  • Damaged frames that need replacing

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

What we seal

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

Different surfaces, different methods

Coping and flashing joints

Coping and flashing joints are included where sealant is the specified fix. They sit in the most exposed positions on the building and need a durable external sealant.

Perimeter joints at frames and structure

Where framed systems such as shopfronts meet the building structure, there is a perimeter joint to seal. We seal those perimeter joints, not the framing or glazing itself.

Work for main contractors and building owners

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Your questions answered

Is Chegworth too small for you to travel to?

Not at all. Chegworth is within our area. 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.

Will you plan work around the academic year at somewhere like Canterbury Christ Church University?

Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Can you look at water coming in around a frame?

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.

Is old mastic on our building likely to contain asbestos?

For older buildings, yes, check before work starts. The dutyholder holds the asbestos register, so ask for it before we start. If asbestos is suspected, work stops until it is tested.

Do you run new sealant over the existing bead?

No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely. Nothing else gives a bond that lasts.

How do I request a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.

Do you seal facades in winter?

Rain and frost can pause external sealing. We plan for weather and keep you updated as the work goes on.

New build and refits around Chegworth

Chegworth is in the South East, one of the UK’s drier regions. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack. Central London is about 37 miles from Chegworth. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme.

Recladding or extending a unit at a site like Roebuck Business Park, 1 mile to the east of Chegworth, brings panel joints and frame perimeters into the programme. When a school such as Harrietsham Church of England Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.

Chegworth is about 6 miles east of Maidstone, in Kent. Our applicators travel to Chegworth for work on facade joints. 931 places across Kent fall within our area, including Chegworth. London is covered too, around 37 miles from Chegworth.

From enquiry to sign-off

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before any cutting starts, with the work itself normally taking anything from a single day to several weeks, depending on joint lengths, access and the weather. Rural sites near Chegworth may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. Product choice follows the joint’s movement and substrate.
  3. The existing bead comes out in full and the joint faces cleaned.
  4. Primer is applied where the maker specifies 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.

Before we start on site

  • Share your working hours and any access restrictions
  • Arrange parking or a loading space
  • Confirm the product named in the specification

Request a quote

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to give us a call on 01277 525 020 or send photos by email with what you know.

Advice

Signs you need facade sealing in Chegworth

Most facade joints fail through age and weathering. UV and weather harden the sealant until it can’t stretch with the building.

Common reasons buildings call us in:

  • Old perimeter mastic that has dried out
  • Sealant pulling away from frames or panels
  • Damp patches beside frames after rain
  • Draughts around frames and panels

Building work at universities like Canterbury Christ Church University (to the north-east of Chegworth) is often timed for the summer, mastic included.

Questions to ask before you book

  • Proof of insurance
  • How they’ll work around occupants
  • Whether old or failed sealant will be cut out, not overlaid
  • What site paperwork they can supply
