Facade sealing in Grateley, done properly

Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure on commercial buildings in Grateley. Where sealant is the specified fix, we also take on coping and flashing joints. We work on cladding panel joints, shopfront frames and stone and brick facade joints, and what we are called in for most is draughts around frames and panels and weathered joints at frame-to-structure perimeters. A specialist sealant contractor works differently from a general builder: on jobs in Grateley, preparation and product choice get the time they need.

Around smaller places like Grateley, building work usually means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

A 12-month guarantee applies to all our work. Should something we installed fail, call 01277 525 020 or send details through our quote form and we’ll come back to it.

Why deal with it now?

Patch repairs over old sealant tend to come back. A full cut-out and reseal costs more on the day but lasts much longer, so you aren’t paying for the same joint twice. For buildings around smaller places like Grateley, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

Pricing facade joints depends on how many there are, their condition and the access. Ask us for a fixed quote.

What you get with us

  • Standard and matched colours in many product ranges
  • Failed material removed, not covered up
  • 12-month guarantee on workmanship
  • Constructionline member for supplier checks

What the job involves on each surface

Cladding panel joints

On sealed panel systems, every joint keeps water out. Failed runs are cut out and rebuilt end to end.

Brick and stone facades

On masonry, the sealant has to suit a porous, textured surface. We avoid acetoxy silicone, which can stain some natural stone, and primers go on where specified.

Building owners, agents and FMs in Grateley

Building owners and managing agents use us on everything from one building to a spread of sites around Grateley. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

What sets the cost

What shapes the price:

  • Whether the work must be split into stages
  • Which sealant the job calls for
  • The total length or number of joints
  • Location, for remote and island sites

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Sending details for a quote

There’s no need for a formal survey. A few details are enough to get going:

  • Anything awkward about access or site hours
  • Any dates the work must fit around
  • The product your specification calls for
  • Asbestos survey details if the building is older

The quickest route to a quote is a few photos and the site postcode. Upload them with the quote form, or call 01277 525 020 or use the quote form if you’d rather talk the job through.

Diagnose, treat, sign off

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. For work around Grateley, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  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. 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.

Preparing the site

  • For older buildings, check the asbestos register before work
  • Tell us what induction or permit system the site runs
  • Confirm the product named in the specification

When to call us in Grateley

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.

What tends to prompt an enquiry:

  • Discoloured or dirty facade joints
  • Water coming in around window frames
  • Failed sealant on precast panel joints
  • Weathered facade joints that have lost their grip

When a school such as Grateley Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.

Choosing a commercial sealant contractor

New build and refits around Grateley

Central London is about 69 miles from Grateley. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand. The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack.

For a contractor working at a hospital such as Andover War Memorial Hospital, 5.4 miles to the north-east of Grateley, perimeter and facade sealing is planned around patients and deliveries.

Grateley is about 6 miles south-west of Andover, in Hampshire. We cover commercial sites throughout Grateley, whether it’s a single job or part of a planned programme. Grateley is one of 723 places we cover in Hampshire for facade joints. There’s a separate page for Southampton, about 20 miles away.

Commercial sites across SP11 are covered for facade joints. Buildings on High Street, Station Road and Hawthorne Close are within our area for facade joints. We also cover Palestine (1 mile south-west), Quarley (1 mile north), Fox (1 mile north-east), Amport (2 miles north-east) and Kentsboro (2 miles south-east) for facade joints. Bigger towns within reach include Winchester (15 miles south-east), Andover (6 miles north-east), Romsey (14 miles south-east), Hyde (15 miles south-east), Tidworth (5 miles north-west) and Weeke (14 miles south-east).
