Mastic sealing in Quidhampton, done properly

Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Our applicators are CSCS-carded and we hold public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. We work on communal entrances and stairwells, external wall and movement joints and window and door perimeters on blocks, and what we’re called in for most is complaints coming in block by block and old repairs sealed over failed mastic. A specialist sealant contractor works differently from a general builder: in Quidhampton, that means joint design, primers and backing rod as standard.

For owners with a single building near Quidhampton, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.

Every job we finish is backed by a 12-month workmanship guarantee, in Quidhampton as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Doing it in-house

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Building owners, agents and FMs in Quidhampton

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.

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules.

From enquiry to sign-off

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts. For work around Quidhampton, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.

  1. First comes a look at the joints and, for older buildings, the asbestos records.
  2. A fixed quote covers the joints, products and order of work.
  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

  • Make sure the joints can be reached
  • Flag any permit to work we’ll need
  • Explain the parking and delivery arrangements

Advice

Common questions from Quidhampton clients

Is Quidhampton too far out for you?

No. Places such as Quidhampton are covered as much as the big towns. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

Can you quote for a block close to Overton station?

Yes, and several blocks can go on one quote. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.

Which sealant will you use?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

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 checks let you plan resealing before leaks or damage.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Can you work to our specification?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.

When can the area be used after sealing?

We’ll confirm how long the chosen product needs to cure.

When to call us in Quidhampton

We often find joints filled solid with no backing rod, so the mastic is glued to the joint bottom too. It can’t stretch properly and splits as the building moves.

Things that usually lead to an enquiry:

  • Draughts at frames across a block
  • Open joints in brickwork or panels
  • Worn sealant at communal door frames
  • Patchy repairs in mismatched sealant

For a school such as Overton Church of England Primary School, perimeter mastic on windows and doors is a holiday job.

Comparing quotes

  • Whether their applicators hold CSCS cards
  • How they’ll work around occupants
  • How the joint faces will be prepared and primed
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

Our contractor checklist

Mastic sealing in Quidhampton: the local picture

Quidhampton lies roughly 53 miles out from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres. The South East is one of the drier parts of the UK. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first.

Blocks of flats and mixed-use buildings often cluster around stations such as Overton station, under half a mile north-east of Quidhampton, and their window and balcony mastic tends to age at the same rate across a building. Older community buildings, Church of St Mary among them, often have frames of mixed ages whose mastic varies.

Quidhampton is about 7 miles west of Basingstoke, in Hampshire. We cover commercial sites throughout Quidhampton. Quidhampton is one of 723 places we cover in Hampshire for mastic joints. We also cover Reading, around 19 miles from Quidhampton.

Honest limits

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

  • Water coming in from the roof or rainwater goods
  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
  • Leaks through the frame itself rather than the perimeter

Not sure which it is? You can call 01277 525 020 or use the quote form and we’ll tell you honestly.

Surface by surface

Tenement and older buildings

Older mastic can contain asbestos, so we check the asbestos register or survey first. Suspect material is tested before work continues.

Communal areas

Communal entrances, stairwells and corridors have joints at door frames, screens, skirting and floor edges. Fresh joints make shared areas look looked after.
