About our facade sealing in Basingstoke

Weather decides a lot in facade sealing. Joints have to be dry and the air and surface temperature within the product’s range. We plan for that and keep you updated. If you have failed seals around shopfront and entrance frames and patch repairs that keep failing, we can put it right. Whoever orders the work in Basingstoke, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

Bigger sites around a town like Basingstoke usually want mastic phased by plot, block or floor. CSCS-carded applicators work to the site’s rules and the specification, and any snags are cleared before handover.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

When to bring in a specialist

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Basingstoke: questions and answers

Do you cover business parks and estates near Basingstoke, such as Thornycroft Industrial Estate?

Yes. We cover Basingstoke and the area around it, including industrial estates, business parks and retail parks such as Thornycroft Industrial Estate. Photos and a short description are enough for a first look.

Can you take on a job at a hospital such as Basingstoke and North Hampshire Hospital?

Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.

Are you fully insured?

Yes. Mastic Doctor is fully insured, public liability included.

Can you work to our specification?

Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it.

Are you CHAS accredited?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member.

Is old mastic on our building likely to contain 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.

How do I request a quote?

There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.

Keeping the joints sound

Keep the joints in good shape with a few simple steps:

  • Don’t wait for a second leak before calling
  • Brief window cleaners about newly sealed joints
  • Record the product and colour used on each elevation
  • Ask about asbestos in pre-2000 mastic

Keep a note of which product went in and when. Future work can then match the product and colour across the elevation.

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Older sealants can contain asbestos, and if it’s suspected, we stop until it has been tested.

Mastic packages on Basingstoke sites

The area within 2 miles of Basingstoke holds plenty of hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. Rainfall across the South East, Basingstoke included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, which is why external dates are agreed with the site manager.

New units and refits on sites such as Thornycroft Industrial Estate (under half a mile south-west of Basingstoke) need their panel and perimeter joints sealed to the specification. On a healthcare site such as Basingstoke and North Hampshire Hospital, which lies north of Basingstoke, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. For contractors at a college like Basingstoke College of Technology (less than half a mile east of Basingstoke), perimeters and internal sealant are timed for the holidays.

What sealant work can’t fix

Honesty saves time and money. New sealant won’t cure:

  • Cracked or spalling substrates that need repair before sealing
  • Specialist high-level access methods
  • Joints whose design needs changing by the specifier

Not sure which it is? You can phone 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.

Where we work in Basingstoke

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

What the job involves on each surface

Precast concrete panels

Precast panel joints have to absorb thermal and structural movement. We use a sealant with the right movement capability, set over backing rod with primer where the product requires it.

Cladding panel joints

On sealed panel systems, every joint keeps water out. We cut out failed joints along their full length and rebuild them to the correct depth.

How the quote is worked out

There’s no standard rate for sealant work, since sites vary so much. What we take into account:

  • Specialist products, such as fire-rated or hygienic sealants
  • Travel to remote or island sites
  • Joint width, depth and condition
  • Induction, permit and paperwork requirements

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

What to include in your enquiry

The more we know, the firmer the quote. Helpful details to send:

  • Photos of the joints, close up and from further back
  • The site address and postcode
  • Any specification or named product
  • Whether an asbestos survey exists

A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or give us a call on 01277 525 020 or use the quote form if you’d rather talk the job through.

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. Town-centre jobs in Basingstoke can mean limited parking and loading, whereas edge-of-town units normally have yard space. Either way, tell us what’s available.

  1. We plan access and the order of elevations with the client.
  2. Weather and temperature are checked against the product’s limits.
  3. Each joint is cut out and the edges inspected.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. We hand over with our 12-month workmanship guarantee.

Getting the site ready

  • Point out parking and an unloading spot
  • Clear stock, furniture or equipment away from the joints
  • Let us know about inductions and permits

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.
