How we handle facade sealing in Sheerwater

Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure on offices, blocks and industrial units. Coping and flashing joints are included where sealant is the specified fix. If you are dealing with draughts around frames and panels and staining on stone next to old sealant, we can put it right, on perimeter joints where frames meet the structure, shopfront frames and coping and flashing joints alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Sheerwater it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Around smaller places like Sheerwater, building work typically 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.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

FAQs: Sheerwater

Is Sheerwater too far out for you?

Not at all. Sheerwater is within our area. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Is Kingsway Business Park, near Sheerwater, within your area?

Yes, sites like Kingsway Business Park are within our area, along with the rest of Sheerwater. Send details of the unit and the work through our quote form for a quick quote.

Will you check whether the sealant is causing the leak?

Yes. Photos help, and you can phone 01277 525 020 or email a schedule or drawings to arrange a visit. Many frame leaks are sealant failures, though not all.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators, as many construction sites ask for.

Is old mastic on our building likely to contain asbestos?

In older non-domestic buildings, old sealant can contain asbestos. Check the asbestos register or survey before it is disturbed, and if anything is suspected, we stop until it’s tested. Removal of asbestos isn’t something we do.

Can staff carry on working while you are here?

Typically, yes. Phased work can be planned so areas stay in use.

Who decides which product is used?

The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Different surfaces, different methods

Precast concrete panels

Precast panel joints have to absorb thermal and structural movement. A sealant of the right movement class goes in over backing rod.

Window and door perimeters

Aluminium, PVC-U and timber frames each have their own preparation needs. Primer goes on where the manufacturer specifies it for that substrate.

On site: what to expect

We bring the products specified for the job, along with primers and backing rod. 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. Rural sites near Sheerwater may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  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.
  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

  • Clear stock, furniture or equipment away from the joints
  • Warn occupants and staff about the work
  • Share your working hours and any access restrictions

Advice

Contractors’ notes for Sheerwater

Sheerwater is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team. Central London is about 22 miles from Sheerwater. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme.

Work at a hotel such as DoubleTree by Hilton Hotel Woking, 1.3 miles south-west of Sheerwater, tends to be programmed around bookings, mastic included. Extensions at sites like Nuffield Health Woking Hospital, 1.4 miles west of Sheerwater, typically sit beside working departments, and the mastic follows strict access rules. Further education sites such as Woking College, 2 miles to the south-west of Sheerwater, are extended and refurbished from time to time, with mastic often programmed into the summer break.

Sheerwater is about 2 miles north-east of Woking, in Surrey. We send applicators to Sheerwater for facade joints, handled exactly as we handle every other area.

When it isn’t the sealant

We check first that sealant really is the fix. It won’t put right:

  • Specialist high-level access methods
  • Work on the window or framing system itself
  • Movement beyond what any sealant can handle

Not sure which it is? You can phone 01277 525 020 or email the details over and we’ll tell you honestly before you book.

What we seal

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

Quoting for work in Sheerwater

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • Location, for remote and island sites
  • How much there is to seal
  • Site requirements such as inductions and permits
  • How accessible the joints are

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

We can often quote from photos and a few details. It helps to include:

  • The product your specification calls for
  • Anything awkward about access or site hours
  • Approximate linear metres or a joint schedule
  • Clear photographs of the problem areas

Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. To get it moving, call the office on 01277 525 020 or send details through our quote form.

Maintenance after handover

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

  • Confirm the survey covers external sealants in older buildings
  • Record the product and colour used on each elevation
  • Clear debris that holds water against joints
  • Share access with other external trades

Record the sealant type and date on the building file. It helps when matching repairs or planning the next reseal without guesswork.

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Older sealants can contain asbestos, and if it’s suspected, we stop until it has been tested.

Doing it in-house

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

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.
