Mastic sealing in New Haw

For over 20 years we have resealed joints for owners, agents and landlords. Our applicators are CSCS-carded, and the work is backed by public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. If you are dealing with open joints in brickwork or panels and damaged joints in communal entrances and corridors, we can put it right, on balcony and threshold joints, window and door perimeters on blocks and shopfronts below residential blocks alike. Whether you call it commercial sealant work, mastic application or joint sealing, the work in New Haw is the same: the right product in a properly prepared joint.

In a smaller place such as New Haw, landlords and agents tend to look after small blocks, flats over shops, sheltered housing and commercial units. Their window perimeters and external joints need renewing as the mastic ages.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Why it’s worth doing now in New Haw

Sealing over failed mastic looks tidy for a while. It won’t grip the old sealant and soon comes away. Cutting out and resealing properly does it once. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.

The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.

What you get with us

  • Products installed to the manufacturer’s instructions
  • Fully insured
  • Coloured sealants to suit the setting, where available
  • Constructionline member

For managing agents and facilities managers

Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. New Haw can form part of a wider programme across Surrey.

Blocks and managed buildings in New Haw

New Haw has six care or nursing homes no more than 2 miles away. For owners and operators of care buildings, window perimeters and external joints are best renewed in planned phases around residents. The South East is one of the drier parts of the UK. Outside work still depends on dry joints, and the sunniest, most exposed sides of a building normally need attention first.

If you look after a block within reach of Byfleet & New Haw station (0.6 miles east of New Haw), frame and balcony mastic can be renewed on one programme. If you are responsible for a building such as All Saints Church, frame and door mastic needs the same attention as any other property. Historic properties like Byfleet Manor, 1.9 miles to the south-east of New Haw, show the age of some local stock, where frame mastic must suit soft brick or stone.

New Haw is about 2 miles south-west of Weybridge, in Surrey. Any commercial site in New Haw is covered, whether it’s a single job or part of a planned programme. New Haw is one of 379 places we cover in Surrey for mastic joints. London is covered too, around 20 miles from New Haw.

Work on mastic joints is covered throughout KT15. Among the streets we cover are Hawthorn Way, Woodham Lane and Mayfield Avenue, and sites on any of them can send details for a fixed quote.

We also cover Byfleet (1 mile south-east), Brooklands (1 mile east), Addlestone (1 mile north), Wisley (2 miles south) and St George's Hill (2 miles east). Bigger towns within reach include Guildford (8 miles south-west), Woking (4 miles south-west), Camberley (10 miles west), Epsom (10 miles east), Ewell (10 miles east) and Egham (6 miles north-west).

How a job runs

Occupied buildings need a little choreography. We sign and contain the area we are in, keep walkways clear and move on in phases so staff and visitors can carry on around us. What matters most for a job in New Haw is a clear list of what needs doing. You will then get a fixed price for the work.

  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. Joints are resealed and tooled.
  6. Each building is checked and signed off with the 12-month guarantee.

What we can’t put right

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Asbestos-containing sealant, which we don’t remove
  • Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
  • Failed window or door frames, which need a window contractor

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

  • Communal kitchens and washrooms
  • External wall and movement joints

Common questions from New Haw clients

Do you work in occupied care homes around New Haw?

Yes. We work around residents’ routines, a room or two at a time. Tell us about any infection-control or safeguarding requirements and we’ll work to them.

Is New Haw too small for you to travel to?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

How do you reach windows on upper floors?

Every block is different. We agree access with you at quote stage so the fixed quote reflects it.

Do you work with property factors and landlords?

We do. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords and work can be quoted per building or as a whole.

Is any job too small?

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

Can you plan resealing across several buildings?

Yes. We survey and price each building, then work through them in order, and the programme can start with the worst.

How long does a job like this take?

That varies with the scale of the job, but the work typically takes one or more days per building, depending on the joint lengths and the access. For bigger or phased jobs, we will set out a timescale with the quote.

Maintenance after handover

A few simple habits keep the new joints working:

  • Start inspections with the most exposed faces
  • Ask residents or tenants to report leaks and draughts early
  • List the paperwork your organisation requires when you send details
  • Group repairs into a planned programme

Log the date and extent of the resealing for each block. That makes future programmes easier to plan and gives you a history.

Failed mastic often goes unnoticed until heavy rain finds it. Resealing when cracking first shows avoids water damage and the complaints that come with it.

Doing it in-house

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

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
