Mastic sealing for Badshot Lea sites

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

Surface by surface

Commercial and mixed-use buildings

Landlords with commercial portfolios have shopfronts, office entrances and external joints to look after. We work across portfolios on a planned basis.

External movement joints

Brickwork, blockwork and panel joints let a building move. Failed sealant in a movement joint lets water in.

Mastic sealing in Badshot Lea

For blocks and buildings in Badshot Lea and across Surrey, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Addresses, photos of typical joints and a rough idea of quantities let us give a quick quote, and site visits can be arranged. Site teams most often ask us about cracked, hardened mastic round windows on a block and the same joint failures repeated across a portfolio, on window and door perimeters on blocks, communal kitchens and washrooms and balcony and threshold joints. For commercial sealant work in Badshot Lea, you deal with one contact from quote to sign-off, whether it’s one building or several.

For owners with a single building near Badshot Lea, we plan to finish in one visit where possible. Send photographs of the frames and joints and we will give a fixed quote.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Frames, entrances and external joints in Badshot Lea

Badshot Lea sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, while the elevations that take the most sun tend to show hardened mastic first. At about 34 miles from central London, Badshot Lea is within reach of the capital. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres; their frame mastic often ages block-wide.

Property owners at sites such as Preymead Industrial Estate (under half a mile north of Badshot Lea) can have mastic renewed between lettings. Churches, halls and community buildings such as St George's Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

Badshot Lea is about 1 mile south of Aldershot, in Surrey. Businesses, contractors and managing agents in Badshot Lea use us for work on mastic joints. Badshot Lea is one of 379 places in Surrey on our list for mastic joints. Our Reading page has more on work in that area (18 miles or so).

If you need mastic sealing in GU9, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee.

Common problems we fix in Badshot Lea

The edges of the material itself sometimes break away, such as crumbling render, brick arrises or frame edges. If the edges are unsound, we say so before quoting the sealing.

Clients typically get in touch after noticing one or more of the following:

  • Window mastic that has split and shrunk
  • Repeated reactive repairs to the same buildings
  • Draught complaints from residents or tenants
  • A mix of products and colours from past repairs

Site managers at schools like Badshot Lea Village Infant School can fit frame mastic into the summer works.

What your quote should include

  • Their pre-qualification and accreditations
  • Whether old or failed sealant will be cut out, not overlaid
  • Their approach to joint depth and backing
  • How they handle RAMS and site documents

Our contractor checklist

What happens if it’s left?

A bead run over old mastic can look like a repair. It won’t grip the old sealant and soon comes away. Full removal and proper preparation is what lasts. For buildings around smaller places like Badshot Lea, 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.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

Why appoint us

  • Sealing commercial buildings since 2005
  • Standard and matched colours in many product ranges
  • Clear, fixed quotes
  • One number for every site we cover

Your questions answered

Will you take on a block within reach of Aldershot station?

Yes. Blocks of any size are within what we do. We work to your notice and access arrangements.

Is Badshot Lea too far out for you?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Can people stay in the building while you reseal?

We plan around people living or working in the building. We agree the programme so you can notify occupiers, and entrances stay in use.

Do you check for asbestos in old sealant?

Some mastics in pre-2000 buildings contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.

How long do sealant joints last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Can weather delay the job?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Doing it in-house

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

What sets the cost

We price every job individually. The things that drive the figure:

  • The site’s rules and procedures
  • Travel to remote or island sites
  • Which sealant the job calls for
  • The size and state of each joint

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Sending details for a quote

A few photos plus some basic facts will normally do. Please tell us:

  • Any specification or named product
  • When you need the work done
  • The type of building and who uses it
  • The asbestos register, for older buildings

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

On site: what to expect

Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For a building around Badshot Lea, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. First we look at the mastic on each building and note what needs replacing.
  2. We send a fixed quote that sets out the joints, the products and the programme.
  3. The programme is fixed with you, including dates you can pass on to residents or tenants.
  4. We remove the old mastic completely and clean the joint faces back.
  5. Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
  6. Each building is checked on completion and the work carries our 12-month guarantee.

What we need from you

  • Confirm the product named in the specification
  • Send your site hours and access windows
  • Move anything stored against the joints
