Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Middle Wallop. Several sites can go on one quote, so there’s one set of paperwork to deal with.

How we handle facade sealing in Middle Wallop

Installing framed glazing systems isn’t part of our work. What we seal are the joints around them: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds with products suited to facade or glazing perimeter joints. We work on cladding panel joints, stone and brick facade joints and coping and flashing joints, and what we’re called in for most is discoloured or dirty facade joints and air leaks through failed facade joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Middle Wallop it comes down to the same thing: the right product in a properly prepared joint.

Construction in and around smaller places such as Middle Wallop is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant.

Signs you need facade sealing in Middle Wallop

New sealant run over old sealant rarely holds. Fresh silicone won’t stick to cured silicone, and the patch soon lifts.

If one of these sounds familiar, it’s time for a closer look:

  • Weathered joints at frame-to-structure perimeters
  • Unsightly perimeter sealant on a visible elevation
  • Draughts around frames and panels
  • Failed sealant on precast panel joints

Hotel extensions and refits, at places such as Fifehead Manor Hotel, which lies north-west of Middle Wallop, normally run between busy periods, so the sealing is squeezed into short windows.

Questions to ask before you appoint anyone

From enquiry to sign-off

We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Jobs in and around smaller places like Middle Wallop are normally planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. We start with photographs, drawings or a visit to see the joints and agree access.
  2. Product choice follows the joint’s movement and substrate.
  3. Failed beads are removed in full and the joint faces cleaned.
  4. Primer goes on where the product data asks for it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. The finished joints are checked with you.

Before we start on site

  • Send asbestos survey details if the building is pre-2000
  • Move anything stored against the joints
  • Let building users know which areas are affected

Aftercare for building managers

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Add perimeter sealant to planned maintenance checks
  • Brief window cleaners about newly sealed joints
  • Combine resealing with other works that need access
  • Investigate damp beside windows promptly

Keep gutters, sills and drainage paths clear. Good drainage keeps water moving off the facade.

Check older buildings for asbestos before disturbing old mastic. Older sealants can contain asbestos, and if it’s suspected, we stop until it has been tested.

Contractors’ notes for Middle Wallop

Middle Wallop 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 the external programme keeps a little slack. Middle Wallop lies roughly 69 miles out from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme.

For contractors at a school such as Wallop Primary School, sealing has to be finished before term starts.

Middle Wallop is about 7 miles south-west of Andover, in Hampshire. If you are looking for facade sealing in Middle Wallop, we can help, as we do across Hampshire. Our Hampshire coverage takes in 723 places, large and small. Our Southampton page has more on work in that area.

How the job changes by surface

Render and coated surfaces

Sealant can only hold as well as the render or paint beneath it. Loose coatings are cleaned back first, and areas needing repair are flagged.

Coping and flashing joints

Sometimes the coping or flashing itself has failed. Where the issue isn’t the sealant, we say so.

Honest limits

Honesty saves time and money. Fresh joints won’t solve:

  • Damaged frames that need replacing
  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Installing or repairing glazing systems

If you are not sure, just call the office on 01277 525 020 or email us and we will give you a straight answer before you book.

Joints and surfaces we work on

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

FAQs: Middle Wallop

Is a smaller place like Middle Wallop outside your area?

No. Small places get the same service as large ones. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Can the mastic package for our job in Middle Wallop follow the site programme?

Yes, we work to the programme and the sequence the site sets. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Will you come and look before quoting?

Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit.

What hours do you work?

The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.

Do you offer coloured sealant?

That depends on the product. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.

Does weather matter for sealant work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Can you just add new sealant on top?

No. A bead run over old sealant soon lifts. Our method is a full cut-out, cleaning, backing and a new bead.
