Facade sealing for commercial buildings in Shedfield

Every facade quote starts with how the joints will be reached. Let us know what access exists or is planned, and any site rules we need to work around, so the price covers the real job. If you have air leaks through failed facade joints and facade joints cracked through the middle, we can put it right, whatever the surface. Facilities teams, main contractors and managing agents in Shedfield tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Sites around smaller places like Shedfield can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Drawings, photos and the programme let us give a fixed quote.

Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Owners, agents and contractors

CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so the building keeps working while we do.

When to bring in a specialist

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

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.

Maintenance after handover

Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:

  • Ask about asbestos in pre-2000 mastic
  • Plan facade sealing alongside redecoration
  • Check that rainwater leaves the facade the way it was designed to
  • Keep the sealant details on the building file

Blocked sills and gutters push water at the joints. Good drainage keeps water moving off the facade instead of soaking the joints.

Check older buildings for asbestos before disturbing old mastic. Some older mastics contain it, and work stops until it’s tested if it’s suspected.

Facade sealing in Shedfield: the local picture

Shedfield sits in one of the drier corners of the country, the South East. 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. Shedfield lies roughly 63 miles out from central London. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes.

Projects at schools like St John the Baptist Church of England Primary School work to term dates, so mastic is programmed tightly. Units on estates such as Grange Farm Business Park, 0.8 miles north-west of Shedfield, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. Hotels like Meon Valley Hotel, 0.7 miles north-west of Shedfield, rarely close for long, so refurbishment mastic is phased floor by floor.

Shedfield is about 4 miles north of Fareham, in Hampshire. If you are looking for facade sealing in Shedfield, we can help, as we do across Hampshire. Across Hampshire, 723 places are covered, including Shedfield. Sites around Southampton have their own page, about 8 miles away.

Questions about Shedfield

Do you cover business parks and estates near Shedfield, such as Grange Farm Business Park?

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

Is Shedfield too far out for you?

No. Places such as Shedfield are covered as much as the big towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

Will you check whether the sealant is causing the leak?

Yes. Photos help, and you can give us a call on 01277 525 020 or use the quote form to arrange a visit. Many frame leaks are sealant failures, though not all, and we will tell you which.

Are you CHAS accredited?

Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.

Are you fully insured?

Yes. We’re fully insured, including public liability cover.

Is it okay to overlay old mastic?

No. A bead run over old sealant soon lifts. We remove the failed sealant, clean the faces, set the depth and reseal.

How do you choose the sealant?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

On site: what to expect

When we get to site, 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 typically taking anything from a single day to several weeks, depending on joint lengths, access and the weather. Rural sites near Shedfield 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. We look at the joints, the drawings and the access before pricing.
  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. The completed runs are checked with you, then the 12-month guarantee applies.

Preparing the site

  • Clear stock, furniture or equipment away from the joints
  • Tell us your opening times and when work is allowed
  • Send asbestos survey details if the building is pre-2000

What the job involves on each surface

Window and door perimeters

Frame materials vary, and so does the preparation. We clean and prime to the sealant maker’s guidance for each surface.

Coping and flashing joints

Where the specification calls for sealant at copings or flashings, we can seal them. These joints take full exposure to weather and need a durable external sealant.
