Sites and facades in and around Brewer Street

The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack. At about 17 miles from central London, Brewer Street is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme.

Hotels like The White Harte Hotel (0.9 miles south of Brewer Street) rarely close for long, so refurbishment mastic is phased floor by floor. For contractors at a school such as Bletchingley Village Primary School, sealing has to be finished before term starts. Extensions at sites like North Downs Hospital, 1.7 miles to the north-east of Brewer Street, typically sit beside working departments, and the mastic follows strict access rules.

Brewer Street is about 2 miles south of Caterham, in Surrey. Businesses, contractors and managing agents in Brewer Street use us for work on mastic packages, as part of our coverage of Surrey.

Construction mastic in Brewer Street

On refurbishments, the mastic package usually includes cutting out old sealant as well as sealing new work. Old beads come out completely, as fresh silicone can’t grip old. New and existing joints then get the same preparation. If you’re dealing with a long mastic snag list close to completion and cracks opening in caulked internal joints, we can put it right, on floor and skirting junctions, sanitary and kitchen joints and brick and block movement joints alike. Most enquiries from Brewer Street start with one failed joint and grow into a wider look at the building: 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 Brewer Street bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Why it’s worth doing now in Brewer Street

Refurbishments sometimes budget for new windows when the frames are sound and only the seal has failed. Sound frames often need only a new perimeter seal. We’ll say so if a frame itself is the problem. Older rural buildings around Brewer Street move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Access often affects the price as much as the sealing: 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.

Why us?

  • Work to your specification and the manufacturer’s guidance
  • Colour options checked against the specified product
  • Fully insured
  • CSCS-carded applicators

Take a look at what affects the cost or how we’re accredited.

When it isn’t the sealant

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:

  • Approving fire stopping as compliant
  • Damage to finishes by other trades after we have sealed
  • Designing joint widths or choosing the specification (that sits with the designer)

Not sure which it is? You can speak to us on 01277 525 020 or email a schedule or drawings and we will tell you honestly.

Surfaces we seal

  • Window and door perimeters
  • Floor and skirting junctions
  • Cladding and panel joints
  • Sanitary and kitchen joints
  • Brick and block movement joints
  • Internal decorators’ caulk

What the job involves on each surface

Fire-rated sealant where specified

Fire-rated sealant is one type of fire-stopping product. Other products are used for some services and gaps, and we’ll tell you if the detail calls for something else. Tell us what records you need and we’ll confirm with the quote.

Bathrooms, en suites and washrooms

Sanitary joints around baths, showers, basins and WCs need anti-mould sanitary silicone. Each joint is prepared, sealed and finished with a neat tooled line, and any bath is loaded with water first where that’s the agreed method.

Questions we are asked in Brewer Street

Do you cover business parks and estates near Brewer Street, such as Brewerstreet Dairy Business Park?

Yes. Estates, retail parks and business parks around Brewer Street, Brewerstreet Dairy Business Park among them, are all within reach. A few photographs and the unit address let us price the work.

Is a smaller place like Brewer Street outside your area?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.

Can you fit around our programme?

We follow the trades through the building. Areas are sealed as they’re released by the site team and we tell you if something stops an area being sealed.

What accreditations do you hold?

Our applicators hold CSCS cards, and we are CHAS accredited and a Constructionline member. We’re also fully insured, with five million pounds of public liability cover.

Do you have public liability insurance?

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

How do you choose the sealant?

The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

What sets the cost

Before we quote, we look at:

  • Whether the work must be split into stages
  • The size and state of each joint
  • Which sealant the job calls for
  • Any access equipment needed

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

What to include in your enquiry

It doesn’t need to be a full survey. These details are enough to start:

  • The product your specification calls for
  • The site address and postcode
  • Clear photos of the problem areas
  • When you need the work done

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, ring 01277 525 020 or send details through our quote form.

Diagnose, treat, sign off

Should maintenance staff do it?

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
