Mastic sealing in Dogmersfield

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

Mastic sealing in Dogmersfield, done properly

Owners and agents usually inherit a building’s mastic rather than choose it and it slowly wears out: it sits round windows and doors, along external joints and through communal areas. Once it cracks, hardens or comes away, draughts and water find a way in along with complaints. We work on communal entrances and stairwells, external wall and movement joints and shopfronts below residential blocks, and the usual reasons a site gets in touch are communal area joints that look neglected and occupiers reporting cold air round windows. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Dogmersfield, preparation and product choice get the time they need.

In and around smaller places like Dogmersfield, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

After the work

Regular inspection catches problems early. Specifically:

  • Make it easy for occupiers to report draughts
  • Keep bins and bikes away from communal door frames
  • Have the asbestos survey to hand for older buildings
  • Plan resealing building by building rather than complaint by complaint

Log the date and extent of the resealing for each block. That makes future programmes easier to plan and shows what was done.

The longer failed joints are left, the more likely the substrate edges break up. Then the edges may need repairing first and the job grows.

What the job involves on each surface

Communal areas

Low-level communal joints get damaged more than most, so they often need renewing sooner.

Estate-wide resealing programmes

A programme can start with the worst buildings and work down. You get one fixed quote per building or for the whole estate.

Signs you need mastic sealing in Dogmersfield

Frames, panels and masonry expand and contract through the year, and the sealant takes up that movement. If the joint or the product wasn’t suited to the movement, it splits long before it should.

Most enquiries start with one or more of the following:

  • Old repairs sealed over failed mastic
  • Occupiers reporting cold air round windows
  • Repeated reactive repairs to the same buildings
  • Estate-wide sealant that is simply worn out

Owners of student blocks near University for the Creative Arts, 4.8 miles to the south-east of Dogmersfield, can schedule frame and external mastic for the summer vacation.

Why it’s worth doing now in Dogmersfield

A bead run over old mastic can look like a repair. It doesn’t bond and usually fails within a short time. Cutting out and resealing properly does it once. Converted and older buildings near places like Dogmersfield tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

Pricing mastic joints depends on quantities, condition and access, plus any specification you are working to. Ask us for a fixed quote.

Block-wide mastic in Dogmersfield

Rainfall across the South East, Dogmersfield included, is lower than in many parts of the UK. 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 37 miles from Dogmersfield. Within reach of London, blocks run by agents and associations are common around stations; their frame mastic often ages block-wide.

Buildings close to stations like Winchfield station (1.7 miles north-west of Dogmersfield) are often flats over shops, with frame mastic to keep sound. If your remit includes a building such as Dogmersfield Church of England Primary School, frame and door mastic can be programmed for the holidays.

FAQs: Dogmersfield

Will you take on work at estates like Hart Shopping Centre, close to Dogmersfield?

Yes, sites like Hart Shopping Centre are within our area, along with the rest of Dogmersfield. Send details of the unit and the work through our quote form for a quick quote.

Is a smaller place like Dogmersfield outside your area?

No. Places such as Dogmersfield are covered as much as the big towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

What guarantee do you give on resealing?

A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.

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.

What’s the quickest route to a quote?

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

Can weather delay the job?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

How long do sealant joints last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
