Facade sealing for businesses in Little Somborne

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

What we can’t put right

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

  • Work on the window or framing system itself
  • Specialist high-level access methods
  • Leaks from roofs, gutters or failed flashings rather than sealant joints

If you are not sure, just speak to us on 01277 525 020 or use the quote form and we’ll give you a straight answer before you book.

What we seal

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

About our facade sealing in Little Somborne

Facade joints are the line of defence between the weather and the building fabric. Once a perimeter seal fails, water tracks in around frames and panels. We remove failed sealant and install a new bead chosen for the joint and how far it moves. Most enquiries involve perimeter joints where frames meet the structure and weathered facade joints that have lost their grip, on shopfront frames, window and door perimeters and perimeter joints where frames meet the structure. A single leaking joint is often how a building in Little Somborne first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Conversions of older rural buildings near smaller places such as Little Somborne bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is typically what’s needed.

A 12-month guarantee applies to all our work. If an installation problem shows up, call 01277 525 020 or use the quote form and we will arrange a return visit.

When to call us in Little Somborne

Sometimes the substrate is the problem: crumbling render, spalling concrete or flaking paint take the sealant with them. We tell you when the edges need repairing before resealing.

Clients usually get in touch after noticing something like this:

  • Hard, chalky sealant that no longer flexes
  • Perimeter sealant that has split or peeled away
  • Draughts around frames and panels
  • Weathered joints at frame-to-structure perimeters

New units and refits on sites such as Balldown Business Centre (2.9 miles east of Little Somborne) need their panel and perimeter joints sealed to the specification.

Questions to ask before you book

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Their public liability cover
  • Who will actually carry out the work
  • Their plan for phasing and protecting the area

Questions to ask before you appoint anyone

From enquiry to sign-off

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. If others near Little Somborne need work, visits can be combined. You’ll have a fixed quote before work starts.

  1. First we review photographs, 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. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Getting the site ready

  • Tell us what induction or permit system the site runs
  • Tell us your opening times and when work is allowed
  • Share the asbestos register for older buildings

Building and refurbishing in Little Somborne

Little Somborne is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack. At about 65 miles from central London, Little Somborne is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme.

New wings at hospitals like Royal Hampshire County Hospital (to the east of Little Somborne) bring long runs of window and panel joints to seal. Projects at colleges like Sparsholt College Rifle Range, 2 miles to the east of Little Somborne, tend to run to term dates, so the mastic is planned tightly.

Little Somborne is about 6 miles west of Winchester, in Hampshire. Commercial clients in Little Somborne can call on us for facade joints. Across Hampshire, 723 places are covered, including Little Somborne. Our Southampton page has more on work in that area, about 12 miles away.

How the job changes by surface

Render and coated surfaces

Where the joint will be painted over, a paintable hybrid or PU sealant may suit. We confirm the product with you before starting.

Cladding panel joints

Where panels are sealed rather than open-jointed, the bead is part of the weather line. We cut out failed joints along their full length and rebuild them with backing and a facade-grade sealant.

How the quote is worked out

What shapes the price:

  • Induction, permit and paperwork requirements
  • Distance, for remote addresses
  • How much existing material needs removing
  • How much there is to seal

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Sending details for a quote

It doesn’t need to be a full survey. A few details are enough to get going:

  • Photos of the joints, close up and from further back
  • Approximate linear metres or a joint schedule
  • Where the site is, with the postcode
  • The product your specification calls for

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.

Your questions answered

Can work at a site such as Sparsholt College Rifle Range fit around teaching?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Do you cover business parks and estates near Little Somborne, such as Balldown Business Centre?

Yes. Our area takes in Little Somborne and its surroundings, with estates and business parks such as Balldown Business Centre included. A few photos and the unit address let us price the work.

Can you look at water coming in around a frame?

Yes. Photos help, and you can call 01277 525 020 or use the quote form to arrange a visit. Failed perimeter sealant is a common cause, but not the only one, and we will be honest about which it is.

Is colour matching possible?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.

Can one quote cover more than one building?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

Should we check old sealant for 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. We don’t remove asbestos-containing materials.

Do you hold CHAS accreditation?

Yes. We are CHAS accredited and a Constructionline member.

Keeping the joints sound

To get the most from the new sealant:

  • Record the product and colour used on each elevation
  • Check the asbestos register before old mastic is disturbed
  • Keep pressure washers away from fresh sealant
  • Don’t wait for a second leak before calling

Record the sealant type and date on the building file. Future work can then match the product and colour across the elevation.

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.
