Construction mastic for businesses in Bordon

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

What the job involves on each surface

Fire-rated sealant where specified

Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested detail. The design and sign-off of fire stopping sit with the designer, principal designer or fire engineer; we work to the specification and the manufacturer’s installation guidance.

Snagging before handover

Damaged, missed or untidy joints make up most snag lists. We price snagging as part of the package or as a separate visit.

Construction mastic for commercial buildings in Bordon

Buyers, tenants and clients notice sealant lines long before they notice the structure. Untidy or missed joints are among the commonest snag items. We seal so the snag list stays short, whatever the size of the scheme. The enquiries we see most involve internal caulk splitting as the building dries out and oversized or tapered gaps around new frames, on brick and block movement joints, window and door perimeters and sanitary and kitchen joints. Looking for mastic applicators who cover Bordon? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.

On a small site around Bordon, the mastic is best done in the fewest visits we can manage. Tell us when scaffold comes down and when decoration finishes, and we will plan around those stages.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Common problems we fix in Bordon

Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A general-purpose silicone on a facade or a caulk in a wet area won’t perform like the specified product. We stick to the specified product, or put any alternative to you first.

Common reasons buildings call us in:

  • External joints sealed in damp or cold conditions that are now failing
  • Snag items on joints that need redoing before handover
  • Old sealant on a refurbishment that needs stripping before new work
  • Frame perimeters left unsealed or poorly sealed

On a healthcare site such as Chase Hospital, 0.5 miles south of Bordon, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Questions to ask before you book

  • Do they follow the manufacturer’s priming guidance?
  • Who will actually carry out the work
  • What the guarantee covers, and for how long
  • What site paperwork they can supply

How to choose a sealant contractor

Mastic packages on Bordon sites

At about 43 miles from central London, Bordon is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme. Bordon sits in one of the drier corners of the country, the South East. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so external mastic is timed for workable conditions and agreed with the site manager.

New units and refits on sites such as Woolmer Trading Estate, less than half a mile south of Bordon, need their panel and perimeter joints sealed to the specification. Projects at schools like Bordon Infant School work to term dates, so mastic is programmed tightly.

Bordon is about 10 miles south-west of Aldershot, in Hampshire. Looking for construction mastic in Bordon? We can help. Bordon is one of 723 places we cover in Hampshire for mastic packages. Sites around Portsmouth have their own page, about 23 miles away.

Anyone looking for construction mastic in GU35 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. If your site is on High Street, Station Road and Cobbett Square or close by, send details and we will quote for mastic packages. You will find Bordon on or near the A325 and B3002, so getting applicators and materials to site is simple.

Further afield, our area takes in Basingstoke (15 miles north-west), Farnborough (13 miles north), Fleet (11 miles north), Aldershot (10 miles north-east), Alton (5 miles north-west) and Petersfield (8 miles south-west).

When it isn’t the sealant

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Deciding which fire-stopping product a penetration needs
  • 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 phone 01277 525 020 or email the details over and we’ll tell you honestly.

Surfaces we seal

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

Questions about Bordon

Is Bordon too far out for you?

No. Places such as Bordon are covered as much as the big towns. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

Is a hospital such as Chase Hospital somewhere you can work?

Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.

What site paperwork can you supply?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

Can you quote from photos?

It depends on the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.

How do you deal with asbestos in old sealant?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

Will you quote for a small job?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

When can you be on site?

The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.

Quoting for work in Bordon

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • How much there is to seal
  • Location, for remote and island sites
  • Access and working height
  • Working within restricted access windows

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

What we need to price the job

Good information means a firmer quote. When you get in touch, include:

  • The type of building and who uses it
  • A wide shot and a close-up of the area
  • The site address and postcode
  • Approximate linear metres or a joint schedule

For a fixed quote, call the office on 01277 525 020 or email the details over with the site address and an outline of the work. Our quote form is another easy route.

General trades versus a specialist

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.

From enquiry to sign-off

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. For a site in Bordon, we plan so the whole job is done in one go where possible. Clear photographs and measurements help us bring the right products.

  1. Drawings, specification and programme come to us.
  2. Quantities are measured and a fixed price returned.
  3. The sequence is agreed with the site manager.
  4. Each area is sealed when it’s released.
  5. Every joint is cleaned, set to depth and sealed with the specified product.
  6. After snagging, the work is handed over under our 12-month guarantee.

What we need from you

  • Send any specification or drawings in advance
  • Explain the parking and delivery arrangements
  • Point out any areas we must not close

Quotes

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.
