Facade sealing for businesses in Criddlestyle

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

Keeping the joints sound

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Keep the sealant details on the building file
  • Walk the elevations once or twice a year
  • Never let anyone seal over old sealant
  • Plan facade sealing alongside redecoration

Hold back any cleaning crew until the joints have had their stated cure time. Pressure washers and harsh cleaners can damage a fresh bead.

Coordinate facade sealing with other external works. Sharing the access keeps the cost down and cuts time on site.

About our facade sealing in Criddlestyle

Most facade joint failures trace back to the joint, not just the sealant. Joint width needs to match how far the joint moves and how far the sealant can stretch, and closed-cell rod sets the depth, keeping the bond to two faces with the ratio the sealant maker recommends, often around 2:1. We work on cladding panel joints, perimeter joints where frames meet the structure and coping and flashing joints, and the usual reasons a site gets in touch are draughts around frames and panels and cladding panel joints that have opened up. A single leaking joint is often how a building in Criddlestyle first comes to us: we look at the rest while we are there and tell you what we find.

Conversions of older rural buildings near smaller places such as Criddlestyle bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

For managing agents and facilities managers

FAQs: Criddlestyle

Do you take on work at healthcare sites like Fordingbridge Hospital?

Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is Criddlestyle too far out for you?

No. Small places get the same service as large ones. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.

Do you seal facades in winter?

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

Do your applicators hold CSCS cards?

Yes. If you need card details for site access, tell us and we will confirm them with the quote.

Will you quote for a small job?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Do you have public liability insurance?

Yes. Our insurance certificate can be sent alongside the quote.

How long does a typical visit take?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

Diagnose, treat, sign off

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. For work around Criddlestyle, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. We plan access and the order of elevations with the client.
  2. Weather and temperature are checked against the product’s limits.
  3. We remove the old bead and check the edges are sound.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. Once signed off, the work carries our 12-month guarantee.

Getting the site ready

  • Send any specification or drawings in advance
  • Explain the parking and delivery arrangements
  • Point out any areas we must not close

Site staff or a sealant specialist?

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Honest limits

Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be one of these:

  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Joints whose design needs changing by the specifier
  • Specialist high-level access methods

If in doubt, call 01277 525 020 or email drawings and photos and we will say what we think before you book.

Surfaces we seal

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

Surface by surface

Brick and stone facades

Joints in natural stone need care to avoid staining. The specified stone-compatible sealant is what we use, with masked edges for a clean line.

Precast concrete panels

Concrete edges can be dusty or weak. We clean back to sound material and flag edges that need repair before sealing.

Mastic packages on Criddlestyle sites

The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack.

Hotel extensions and refits, at places such as Greyhound Hotel (0.9 miles west of Criddlestyle), normally run between busy periods, so the sealing is squeezed into short windows. On a healthcare site such as Fordingbridge Hospital, 1 mile west of Criddlestyle, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. When a school such as The Burgate School and Sixth Form is extended or refurbished, the mastic package is often squeezed into the holidays.
