Mastic sealing around Lower Bourne: points for this area

At about 37 miles from central London, Lower Bourne is within reach of the capital. Within reach of London, blocks run by agents and associations are common around stations; their frame mastic often ages block-wide. Lower Bourne sits in one of the drier corners of the country, the South East. Outside work still depends on dry joints, and the sunniest, most exposed sides of a building usually need attention first.

Older community buildings, St Martin by the Green among them, often have frames of mixed ages whose mastic varies. If you manage student housing near a university such as University for the Creative Arts (1.5 miles north-west of Lower Bourne), the summer turnaround is the time for mastic. Site managers at schools like Farnham College can fit frame mastic into the summer works.

Lower Bourne is about 1 mile south of Farnham, in Surrey. Lower Bourne sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Our Surrey coverage takes in 379 places, from busy centres to rural villages. For work in that direction, see our Reading page (19 miles or so).

Work on mastic joints is covered throughout GU10 and GU9, for business premises of every kind. Streets here include Fox Road, Ford Lane and Kiln Lane. With the A287 nearby, Lower Bourne is easy to get to with materials and equipment. If your building is just outside Lower Bourne, we cover Tilford Reeds (1 mile south-east), Shortfield Common (1 mile south), Millbridge (2 miles south), Tilford (2 miles east) and Frensham (2 miles south).

How we handle mastic sealing in Lower Bourne

Different joints need different sealants. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, and MS polymer sealants stick well to many substrates and often take paint, and colours are confirmed for whichever product is used. If you are dealing with mastic failing across several blocks on an estate and water getting in round frames after rain, 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: on jobs in Lower Bourne, preparation and product choice get the time they need.

Converted and older buildings in and around Lower Bourne often put modern windows into old walls. Perimeter joints need a sealant that suits both frame and masonry.

The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Why act early in Lower Bourne

Failed perimeter mastic lets cold air in around frames and the windows usually get the blame. In many cases, new perimeter sealant deals with it when the frames themselves are sound. In a smaller place such as Lower Bourne, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.

The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

Why appoint us

  • Matching to RAL references, product permitting
  • Health and safety: CHAS accredited
  • Sealing commercial buildings since 2005
  • Constructionline member

Questions about Lower Bourne

We manage a building near Farnham station. Can you help?

Yes. Blocks of any size are within what we do. Send the address, photos of the elevations and your access arrangements, and we’ll give a fixed quote.

Can you work at a site such as Hookstile Trading Estate, by Lower Bourne?

Yes. We cover Lower Bourne and the area around it, including industrial estates, business parks and retail parks such as Hookstile Trading Estate. A few photographs and the unit address let us price the work.

Does the weather affect the work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Can you plan resealing across several buildings?

We can. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

Can people stay in the building while you reseal?

Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so it can be arranged.

How long does a typical visit take?

That varies with the scale of the job, but the work normally takes a few days for most blocks, with larger programmes scheduled building by building. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

How a job runs

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a job in Lower Bourne, the main thing is a clear picture of the work, so send photos of each area. A fixed quote follows.

  1. We check the asbestos register for older buildings and look at the joints.
  2. The products and programme are set out in a fixed quote.
  3. We strip out the old sealant.
  4. Joint faces are cleaned, backed and resealed.
  5. Buildings are completed in turn.

What we need from you

  • Tell us your opening times and when work is allowed
  • Move anything stored against the joints
  • Flag any permit to work we’ll need

Getting a fixed quote

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.

How the job changes by surface

Commercial and mixed-use buildings

Commercial buildings have mastic at shopfronts, entrances and external joints. A planned programme suits multi-building portfolios.

Tenement and older buildings

Older buildings, including Scotland’s sandstone tenements, have their own joint details. We look at the substrate before choosing a sealant.

Work for main contractors and building owners

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

What sealant work can’t fix

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

  • Failed window or door frames, which need a window contractor
  • Substrate edges that need repairing first
  • Materials that need asbestos testing before work

If in doubt, call 01277 525 020 or email drawings and photos and we will say what we think.

What we seal

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

How the quote is worked out

There’s no standard rate for sealant work, because every site is different. What we take into account:

  • Phasing around occupants
  • How accessible the joints are
  • Backing rod, priming and other preparation
  • Site requirements such as inductions and permits

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Details that help us quote

To price the job accurately, we need a clear picture of the site. Useful things to include:

  • The postcode of the building
  • Your programme or deadline
  • Clear photos of the problem areas
  • Approximate linear metres or a joint schedule

A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or call the office on 01277 525 020 or email drawings and photos to discuss it first.
