Mastic sealing for businesses in Bentley

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

What happens if it’s left?

Failed perimeter mastic lets cold air in around frames, and they often blame the windows. In many cases, new perimeter sealant deals with it when the frames themselves are sound. Halls, stores and units around places like Bentley may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Why appoint us

  • CHAS accredited
  • Constructionline member for supplier checks
  • RAL and finish matching where the product range allows
  • Clear, fixed quotes

Mastic sealing in Bentley

In buildings from before 2000, some old mastics contain asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. We don’t remove asbestos-containing materials. Most enquiries involve occupiers reporting cold air round windows and open joints in brickwork or panels, across balcony and threshold joints, communal kitchens and washrooms and window and door perimeters on blocks. Most enquiries from Bentley start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

For buildings around smaller places like Bentley, we group work so one trip covers it. Send photographs of the frames and joints and we will give a fixed quote.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Blocks and managed buildings in Bentley

Bentley sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first. Central London is about 40 miles from Bentley. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres.

If your remit includes a building such as Bentley Church of England Primary School, frame and door mastic can be programmed for the holidays. Blocks of flats and mixed-use buildings often cluster around stations such as Bentley (Hampshire) station, 0.8 miles south-east of Bentley, and their window and balcony mastic tends to age at the same rate across a building.

Bentley is about 4 miles west of Farnham, in Hampshire. Businesses, contractors and managing agents in Bentley use us for work on mastic joints, as part of our coverage of Hampshire. Across Hampshire, 723 places are covered, including Bentley. Sites around Reading have their own page, about 18 miles away.

We take on mastic joints across the GU10 and GU34 postcode area. For a building on Station Road, Broadlands Close and Eggars Field or nearby, we can quote for mastic joints. Close to Bentley, our area also takes in Isington (1 mile south-west), Blacknest (1 mile south-east), Bucks Horn Oak (2 miles south-east), Holt Pound (2 miles east) and Binsted (2 miles south). Bigger towns within reach include Basingstoke (11 miles north-west), Farnborough (9 miles north-east), Fleet (6 miles north), Aldershot (6 miles north-east), Alton (5 miles south-west) and Petersfield (13 miles south).

Looking after the joints

After handover, these steps help:

  • Share your contractor requirements early
  • Group repairs into a planned programme
  • Make it easy for occupiers to report draughts
  • Log resealing dates block by block

If a joint we sealed fails within 12 months, tell us and we will look at it. After that, regular inspection keeps the programme on track.

Water getting in round frames can damage plaster, decoration and the frames themselves. Resealing early keeps the job small.

Signs you need mastic sealing in Bentley

In communal areas, joints take knocks from bins, bikes, buggies and deliveries, with joints near the floor and around doors suffering most. Regular cleaning wears them further.

Clients typically get in touch after noticing something like this:

  • Repeated reactive repairs to the same buildings
  • Draught complaints from residents or tenants
  • Leaks at window and door perimeters
  • Open joints in brickwork or panels

For owners of several units at places like Bentley Business Park (less than half a mile south-east of Bentley), one programme can deal with frame and external mastic across the lot.

Our contractor checklist

Your questions answered

Will you take on a block within reach of Bentley (Hampshire) station?

Yes, we work for agents, landlords and housing associations with blocks of every size. Send the address, photos of the elevations and your access arrangements, and we will give a fixed quote.

Is Bentley Business Park, near Bentley, within your area?

Yes. Our area takes in Bentley and its surroundings, with estates and business parks such as Bentley Business Park included. A few photographs and the unit address let us price the work.

Can you send RAMS and CSCS details before starting?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We hold CHAS accreditation and Constructionline membership.

Which sealant will you use?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Do you check for asbestos in old sealant?

We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.

Can you take on resealing for a block portfolio?

Yes, that’s exactly who this service is for. We work through buildings in a planned order with dates agreed in advance.

Is mastic sealing guaranteed?

Our workmanship carries a 12-month guarantee, backed by public liability insurance.

Diagnose, treat, sign off

Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Rural sites near Bentley may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. A building-by-building inspection lists the failed joints.
  2. You get a fixed quote, per block or for the whole programme.
  3. We agree the programme and dates with you.
  4. Old mastic is removed and the joint faces prepared.
  5. New sealant goes in with backing rod and primer where needed.
  6. Each building is checked and signed off with the 12-month guarantee.

Preparing the site

  • Explain the parking and delivery arrangements
  • For older buildings, check the asbestos register before work
  • Send any specification or drawings in advance

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.

Advice

Quoting for work in Bentley

Your fixed quote is built from the real scope. It takes account of:

  • Travel to remote or island sites
  • Access and working height
  • Which sealant the job calls for
  • Joint width, depth and condition

The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Sending details for a quote

For an accurate fixed quote, we need to understand the site. Send us:

  • Whether an asbestos survey exists
  • A wide shot and a close-up of the area
  • The site address and postcode
  • Specification clauses that apply

A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or speak to us on 01277 525 020 or email the details over if you’d rather talk the job through.

Honest limits

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

  • Masonry that has broken away beside the joint
  • Asbestos-containing sealant, which we don’t remove
  • Failed window or door frames, which need a window contractor

If in doubt, speak to us on 01277 525 020 or email drawings and photos and we will say what we think before you book.

What we seal

  • Balcony and threshold joints
  • Shopfronts below residential blocks
  • Communal entrances and stairwells
  • External wall and movement joints
  • Communal kitchens and washrooms
  • Window and door perimeters on blocks
