Facade sealing for businesses in Thorpe

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

When it isn’t the sealant

Being straight saves everyone time. New sealant won’t cure:

  • Specialist high-level access methods
  • Water getting in through cracked render or porous masonry
  • Replacing glass or failed glazing units

Not sure which it is? You can call the office on 01277 525 020 or send details through our quote form and we will tell you honestly before you book.

Joints and surfaces we work on

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

Facade sealing for commercial buildings in Thorpe

A good facade joint depends on design as much as product. Joint width needs to match how far the joint moves and how far the sealant can stretch, while rod fixes the depth and stops the bead sticking to the rear. We work on window and door perimeters, stone and brick facade joints and perimeter joints where frames meet the structure, and the failures we are asked to look at most are unsightly perimeter sealant on a visible elevation and gaps between rainscreen or cladding panels. For commercial sealant work in Thorpe, you deal with one contact from quote to sign-off, whether it’s one building or several.

In the countryside around places like Thorpe, 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.

Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

Cost factors for facade joints

What shapes the price:

  • Removal of failed or old sealant
  • Quantities, in metres or numbers
  • Whether the work must be split into stages
  • The size and state of each joint

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Details that help us quote

A good diagnosis starts with the right details. Let us know:

  • Approximate linear metres or a joint schedule
  • When you need the work done
  • Where the site is, with the postcode
  • The product your specification calls for

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.

When to bring in a specialist

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

For most general trades, sealant is a sideline. 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.

When to call us in Thorpe

Not every failure is in the sealant: if the edge of the render, concrete or coating breaks away, the bead goes with it. We tell you when the edges need repairing before resealing.

Things that usually lead to an enquiry:

  • Weathered joints at frame-to-structure perimeters
  • Old perimeter mastic that has dried out
  • Cold air coming in at window perimeters
  • Water coming in around window frames

Projects at colleges like Strode's College (1.8 miles north-west of Thorpe) tend to run to term dates, so the mastic is planned tightly.

Before you book anyone

  • Whether old or failed sealant will be cut out, not overlaid
  • Are they CHAS accredited or on Constructionline?
  • The named product and why it was chosen
  • Do they follow the manufacturer’s priming guidance?

Questions to ask before you appoint anyone

After the work

Once the work is signed off, a little attention goes a long way:

  • Record the product and colour used on each elevation
  • Walk the elevations once or twice a year
  • Combine resealing with other works that need access
  • Ask about asbestos in pre-2000 mastic

Include facade joints in your planned maintenance inspections. Watch for splits, gaps at the edges, hardening and discolouration; note where they appear.

Get the joint design right when resealing: the right width, backing rod and a sealant with enough movement capability. A well-designed joint lasts longer than a like-for-like copy of a failed one.

Facades, frames and programmes in Thorpe

Thorpe is about 20 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme. Thorpe has a good number of hotels close by, all within 2 miles. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight.

When a school such as Thorpe CofE Aided Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. Hospital estates such as St Peter's Hospital A&E (to the south of Thorpe) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

Our process

In a busy building, 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 reopened once the sealant allows before the next one starts. For work around Thorpe, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.

  1. We start with photographs, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. Failed beads are removed in full and both faces cleaned back.
  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.

What we need from you

  • Tell us which areas need to stay in use
  • Let building users know which areas are affected
  • Send asbestos survey details if the building is pre-2000

Advice

Questions we are asked in Thorpe

Does your area include sites such as Egham Business Park, near Thorpe?

Yes. Estates, retail parks and business parks around Thorpe, Egham Business Park among them, are all within reach. A few photographs and the unit address let us price the work.

Can you work on a hospital site such as St Peter's Hospital A&E?

Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Are you CHAS accredited?

Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Do you guarantee your work?

Yes. Our workmanship is backed for 12 months.

Which sealant will you use?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Do you need to see the site first?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit before quoting.

Can you look at water coming in around a frame?

Yes. We check the sealant joints and report what we find. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.
