Facade sealing for Grayshott sites

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

Facade sealing in Grayshott, done properly

Most facade joint failures trace back to the joint, not just the sealant. The width has to suit the expected movement and the sealant’s movement capability, and closed-cell rod sets the depth, keeping the bond to two faces. If you have damp patches beside frames after rain and perimeter joints where frames meet the structure, we can put it right, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Grayshott, that means joint design, primers and backing rod as standard.

Conversions around smaller places like Grayshott often join new frames to old masonry or timber, and the sealant at those junctions has to cope with two materials that move differently.

Our workmanship is guaranteed for 12 months, in Grayshott as everywhere else we work. If our installation lets you down in that time, we return and fix it.

How the quote is worked out

We price every job individually. The main factors are:

  • Removal of failed or old sealant
  • Backing rod, priming and other preparation
  • Whether the work must be split into stages
  • How accessible the joints are

What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a quote when you are ready.

Sending details for a quote

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • The postcode of the building
  • Specification clauses that apply
  • Approximate linear metres or a joint schedule
  • Whether the building will be occupied during the work

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call 01277 525 020 or email drawings and photos.

Why deal with it now?

Scaffold or access already on site makes resealing much simpler. Combine it with planned external works and you only arrange access once. Small buildings around Grayshott suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

When to bring in a specialist

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Signs you need facade sealing in Grayshott

Sun, rain and temperature swings wear facade sealant down over the years. The bead hardens, chalks on the surface and loses the flexibility to follow the joint.

Typical triggers for a call:

  • Leaks at window and door perimeters
  • Weathered facade joints that have lost their grip
  • Patch repairs that keep failing
  • Cladding panel joints that have opened up

When a school such as Grayshott Church of England Controlled Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.

Your questions answered

Is Kings Road Industrial Estate, near Grayshott, within your area?

Yes. Estates, retail parks and business parks around Grayshott, Kings Road Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.

Is a smaller place like Grayshott outside your area?

No. Places such as Grayshott are covered as much as the big towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Is old mastic on our building likely to contain asbestos?

It’s worth checking in any building from before 2000. The dutyholder holds the asbestos register. If asbestos is suspected, work stops until it is tested.

How do we ask for a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.

Do you have public liability insurance?

Yes. We are fully insured, including public liability cover.

Is the work guaranteed?

Yes. Workmanship is guaranteed for 12 months.

Will you check whether the sealant is causing the leak?

Yes. Photos help, and you can phone 01277 525 020 or send details through our 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.

Contractors’ notes for Grayshott

At about 39 miles from central London, Grayshott is within reach of the capital. 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. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager.

Hospital estates such as Holy Cross Hospital (1.6 miles south-east of Grayshott) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. Hotel extensions and refits, at places such as Devil's Punchbowl Hotel, 1 mile to the east of Grayshott, normally run between busy periods, so the sealing is squeezed into short windows.

When it isn’t the sealant

We check first that sealant really is the fix. It won’t put right:

  • Cracked or spalling substrates that need repair before sealing
  • Installing or repairing glazing systems
  • Leaks from roofs, gutters or failed flashings rather than sealant joints

Not sure which it is? You can give us a call on 01277 525 020 or email us and we’ll tell you honestly.

Joints and surfaces we work on

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

From enquiry to sign-off

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Several jobs near Grayshott can be grouped on one trip. Tell us your site hours and we’ll plan around them.

  1. We plan access and the order of elevations with the client.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. We remove the old bead and check the edges are sound.
  4. Faces are cleaned, primed where needed and backed.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. Once signed off, the work carries our 12-month guarantee.

Preparing the site

  • Clear stock, furniture or equipment away from the joints
  • Point out any areas we must not close
  • Tell us what induction or permit system the site runs
