Common questions from Sandleford clients

Do you work for managing agents with blocks near Newbury station?

Yes, and several blocks can go on one quote. We work to your notice and access arrangements.

Do you cover business parks and estates near Sandleford, such as Newbury Retail Park?

Yes. Our area takes in Sandleford and its surroundings, with estates and business parks such as Newbury Retail Park included. A few photographs and the unit address let us price the work.

How long do sealant joints last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Can you send RAMS and CSCS details before starting?

We’re CHAS accredited, a Constructionline member and carry public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

How soon can the area be used again?

Curing time varies by product, and we confirm it on the day.

Will residents or tenants be disturbed?

Occupiers stay in the building throughout. If any flats or units need access, we’ll tell you in advance so it can be arranged.

Can weather delay the job?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Mastic sealing in Sandleford

We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. Many prefer a planned programme to one-off visits and we quote and schedule each building in turn. Most enquiries involve worn sealant at communal door frames and draught complaints from residents or tenants, on communal kitchens and washrooms, balcony and threshold joints and external wall and movement joints. For commercial sealant work in Sandleford, you deal with one contact from quote to sign-off, whether it’s one building or several.

Around smaller places like Sandleford, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Owners, agents and contractors

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

We work for building owners and managing agents on sealant work across single buildings or whole portfolios. Several sites can go on one quote, so there’s one set of paperwork to deal with.

What we can’t put right

Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:

  • Glazing that needs replacing
  • Roof leaks, gutters or failed flashings that aren’t sealant joints
  • Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)

If in doubt, call the office on 01277 525 020 or email drawings and photos and we will say what we think before you book.

What we seal

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

Keeping the joints sound

Once the work is signed off, a little attention goes a long way:

  • Plan resealing building by building rather than complaint by complaint
  • Look at the sunniest and most exposed elevations first
  • Make it easy for occupiers to report draughts
  • Reduce knocks to communal area joints

Encourage occupiers to report water or draughts at frames. A quick report keeps a small repair small.

Leaks at window perimeters spoil finishes and can affect frames. Resealing early keeps the job small.

Surface by surface

Planned maintenance

Mastic wears out like any building component; how fast comes down to movement, weather, UV and the product. Regular inspection is the best way to plan resealing.

Tenement and older buildings

Traditional buildings have joints that need a careful approach. The material either side of the joint shapes the product choice.

How a job runs

When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work normally takes a day or two for a single block, longer for an estate programme. If others near Sandleford need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. We inspect each building and record the joints that have failed.
  2. You get a fixed quote, per block or for the whole programme.
  3. Dates and areas are agreed so occupiers can be told.
  4. Failed sealant is removed and the faces prepared.
  5. Joints are resealed and tooled.
  6. Each building is checked and signed off with the 12-month guarantee.

What we need from you

  • Send any specification or drawings in advance
  • Flag any permit to work we’ll need
  • Point out parking and an unloading spot

Ask for a quote

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Mastic sealing around Sandleford: how the place shapes the job

Sandleford is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, while the elevations that take the most sun tend to show hardened mastic first. Sandleford is about 53 miles from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres; their frame mastic often ages block-wide.

Historic properties like Shaw House, 2.4 miles north of Sandleford, show the age of some local stock, where frame mastic must suit soft brick or stone. Trustees of buildings like St Gabriel's School can bring frame and external mastic into a planned maintenance list. Buildings close to stations like Newbury station, 1.4 miles to the north of Sandleford, are often flats over shops, with frame mastic to keep sound.

Sandleford is about 1 mile south of Newbury, in West Berkshire. Across the RG19 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Sandleford is one of 140 places we cover in West Berkshire for mastic joints. There’s a separate page for Reading, about 15 miles away.

Work on mastic joints is covered throughout RG19, RG20 and RG14, for business premises of every kind. For a building on Priory Place, Laurel Gardens and Sandleford Lodge Park or nearby, we can quote for mastic joints. We also cover Greenham (1 mile north-east), Newtown Common (1 mile south-west), Wash Common (1 mile west), Burghclere Common (1 mile south) and Newbury (1 mile north). Bigger towns within reach include Thatcham (3 miles north-east), Burghfield Common (11 miles east), Hungerford (9 miles west), Fords Farm (13 miles east), Little Heath (13 miles north-east) and Calcot (12 miles east).

General trades versus a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

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.
