Facade sealing for Highwood sites

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

Aftercare for building managers

After handover, a little attention goes a long way:

  • Never let anyone seal over old sealant
  • Record the product and colour used on each elevation
  • Don’t wait for a second leak before calling
  • Keep pressure washers away from fresh sealant

After heavy weather, check vulnerable elevations for signs of water inside. An early report normally means a small reseal rather than a bigger repair.

Check older buildings for asbestos before disturbing old mastic. Older sealants can contain asbestos.

About our facade sealing in Highwood

Water ingress at window frames is a frequent reason facilities managers contact us. Very often the perimeter bead has cracked or lost its grip, but not always. We’ll tell you if we think the leak is coming from somewhere sealant won’t fix. The enquiries we see most involve perimeter sealant that has split or peeled away and unsightly perimeter sealant on a visible elevation, across cladding panel joints, window and door perimeters and perimeter joints where frames meet the structure. Whoever orders the work in Highwood, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

Construction in and around smaller places such as Highwood is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Work for main contractors and building owners

If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

When to call us in Highwood

Most facade joints fail through age and weathering. UV and weather harden the sealant until it can’t stretch with the building, and cracks or adhesion loss follow.

Things that typically lead to an enquiry:

  • Leaks at window and door perimeters
  • Sealant pulling away from frames or panels
  • Old perimeter mastic that has dried out
  • New sealant peeling off old mastic

Historic houses such as Avon Tyrrell House, 4.6 miles to the south of Highwood, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

Questions to ask before you appoint anyone

Questions about Highwood

Do you cover business parks and estates near Highwood, such as Headlands Business Park?

Yes. Our area takes in Highwood and its surroundings, with estates and business parks such as Headlands Business Park included. A few photographs and the unit address let us price the work.

Can you work on a hospital site such as St Leonard's Hospital?

Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

How much does the work cost?

It depends on the job: quantities, access, the product and any phasing. Call for a fixed quote.

How long before the joints can be used?

We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.

Is your workmanship covered by a guarantee?

Yes. Our workmanship is backed for 12 months on every job.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Can one quote cover more than one building?

Yes. A group of buildings can go on one quote, and you deal with one contact throughout.

What we can’t put right

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

  • Render or concrete edges that have broken away
  • Joints whose design needs changing by the specifier
  • Providing access systems for the work

If you are not sure, just give us a call on 01277 525 020 or send details through our quote form and we’ll give you a straight answer.

Joints and surfaces we work on

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

Our process

On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself usually taking anything from a single day to several weeks, depending on joint lengths, access and the weather. Rural sites near Highwood may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. The old bead is cut away completely, not overlaid.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. We walk the finished joints with you before handing over.

What we need from you

  • Point out any areas we must not close
  • Arrange parking or a loading space
  • Tell us your opening times and when work is allowed

Contractors’ notes for Highwood

Highwood is in the South East, one of the UK’s drier regions. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager.

For a contractor working at a hospital such as St Leonard's Hospital, which lies south-west of Highwood, perimeter and facade sealing is planned around patients and deliveries. For contractors at a school such as Poulner Infant School, sealing has to be finished before term starts.

Highwood is about 2 miles north-east of Ringwood, in Hampshire. Looking for facade sealing in Highwood? We can help. Highwood is one of 723 places in Hampshire on our list. There’s a separate page for Southampton, roughly 16 miles from Highwood.
