Mastic sealing near Tongham

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

When to bring in a specialist

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Mastic sealing in Tongham, done properly

Treatment starts with a proper look: which joints have failed, why, and whether sealant is the right answer. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed, with backing rod setting the depth where it’s needed. The enquiries we see most involve worn sealant at communal door frames and water getting in round frames after rain, across communal kitchens and washrooms, communal entrances and stairwells and shopfronts below residential blocks. One point of contact handles commercial sealant work in Tongham from the first photos to the final walk-round, whether it’s one building or several.

Owners with buildings around smaller places like Tongham often group mastic work so one visit covers several properties. Send the addresses and photographs and we’ll quote for all of them together.

A 12-month guarantee applies to all our work. Should something we installed fail, ring 01277 525 020 or email drawings and photos and we’ll come back to it.

From enquiry to sign-off

On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work normally takes one or more days per building, depending on the joint lengths and the access. Several jobs near Tongham can be grouped on one trip. Mention the building’s opening times and we will work within them.

  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. Failed mastic is removed completely.
  4. Joint faces are cleaned, backed and resealed.
  5. Buildings are completed in turn.

Before we start on site

  • Send any specification or drawings in advance
  • Tell us your opening times and when work is allowed
  • Point out parking and an unloading spot

Getting a fixed quote

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

Advice

Mastic sealing in Tongham: the local picture

Central London is about 33 miles from Tongham. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres. Tongham has three care or nursing homes no more than 2 miles away. Frame mastic on care buildings is best renewed elevation by elevation, with the manager deciding timings.

For agents with blocks near Ash station, 1.4 miles to the north-east of Tongham, a block-wide mastic programme deals with frames, balconies and entrances in one go. If you are responsible for a building such as Church of St Paul, frame and door mastic needs the same attention as any other property.

Why it’s worth doing now in Tongham

Dealing with failed joints one report at a time is slow and scattered. A planned programme treats each building once and is simpler to manage and budget. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.

What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.

Why appoint us

  • Colours chosen to suit frames, cladding or finishes where possible
  • Colour agreed before work starts
  • CSCS-carded applicators
  • Commercial sealant work since 2005

See what affects the cost and how we’re accredited.

What sealant work can’t fix

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Frames that are rotten, warped or broken
  • Water coming in from the roof or rainwater goods
  • Substrate edges that need repairing first

If you’re not sure, just call 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.

What we seal

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

Common problems we fix in Tongham

Occasionally the substrate fails, not the sealant, such as crumbling render, brick arrises or frame edges. If the edges are unsound, we say so before quoting the sealing.

Any of the following is a good reason to get the joints checked over:

  • The same joint failures repeated across a portfolio
  • Failed external movement joints
  • Communal area joints that look neglected
  • Cracked, hardened mastic round windows on a block

If you own or manage units on a site such as Manor Farm Business Centre, under half a mile to the south of Tongham, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

Comparing quotes

  • Proof of insurance
  • Health and safety accreditation such as CHAS
  • Do they follow the manufacturer’s priming guidance?

Common questions from Tongham clients

Do you work in occupied care homes around Tongham?

Yes. We work around residents’ routines, a room or two at a time. Noise and disruption are kept to a minimum.

Is Tongham too far out for you?

Not at all. Tongham is within our area. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

How soon can the area be used again?

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

Will you quote for a small job?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

Do you do block-wide mastic programmes?

Yes, planned programmes suit estates and portfolios. You get a fixed quote per building or for the whole job.

What guarantee do you give on resealing?

Our workmanship carries a 12-month guarantee and we hold public liability insurance.
