Mastic sealing for businesses in Crookham

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

What the job involves on each surface

Communal areas

Entrance doors, screens and corridor junctions in communal areas all have sealant joints. Tidy, sound joints keep them looking cared for.

Commercial and mixed-use buildings

Landlords with commercial portfolios have shopfronts, office entrances and external joints to look after. A planned programme suits multi-building portfolios.

Mastic sealing in Crookham

In buildings from before 2000, some old mastics contain asbestos. Before we disturb it, we ask to see the asbestos register or survey and if it’s suspected, work stops until it’s tested. We don’t remove asbestos-containing materials. Site teams most often ask us about occupiers reporting cold air round windows and communal area joints that look neglected, on balcony and threshold joints, external wall and movement joints and communal kitchens and washrooms. Facilities teams, main contractors and managing agents in Crookham tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Around smaller places like Crookham, 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.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

For owners and agents in Crookham

Rainfall across the South East, Crookham included, is lower than in many parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, while the elevations that take the most sun tend to show hardened mastic first. Central London is about 49 miles from Crookham. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres; their frame mastic often ages block-wide.

If you look after a block within reach of Thatcham station, which lies north-west of Crookham, frame and balcony mastic can be renewed on one programme. With historic buildings such as Shaw House, 5 miles to the north-west of Crookham, in the wider area, owners of older properties around Crookham should expect mastic to need a product that suits old masonry.

Crookham is about 3 miles south-east of Thatcham, in West Berkshire. We send applicators to Crookham for mastic joints, handled exactly as we handle every other area. 140 places across West Berkshire fall within our area, including Crookham. Reading is covered too, some 12 miles away.

We take on mastic joints across the RG7 and RG19 postcode area, for business premises of every kind. We cover commercial and managed buildings on Crookham Common Road and Hyde End Lane. Sites close to Crookham are covered too, including Hyde End (1 mile south-east), Goose Hill (1 mile south-west), Mill Green (1 mile south-west), Ashford Hill (2 miles south-east) and Plastow Green (2 miles south-west). A short drive away, we cover Newbury (5 miles west), Thatcham (3 miles north-west), Burghfield Common (7 miles east), Speenhamland (5 miles north-west), Hungerford (13 miles west) and Fords Farm (9 miles north-east).

What affects the price in Crookham

Before we quote, we look at:

  • The size and state of each joint
  • Location, for remote and island sites
  • How much existing material needs removing
  • Quantities, in metres or numbers

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

What we need to price the job

We can often quote from photographs and a few details. Please tell us:

  • Approximate linear metres or a joint schedule
  • Where the site is, with the postcode
  • Any specification or named product
  • Your programme or deadline

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.

Should maintenance staff do it?

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

When to call us in Crookham

Communal entrances and corridors see a lot of wear, with joints near the floor and around doors suffering most. Regular cleaning wears them further.

These are often picked up first by site or facilities staff:

  • A mix of products and colours from past repairs
  • Failed external movement joints
  • Window mastic that has split and shrunk
  • Leaks at window and door perimeters

For a school such as Brimpton C.E. Primary School, perimeter mastic on windows and doors is a holiday job.

Questions to ask before you book

  • Can the work be phased to keep areas open?
  • Will failed sealant be removed rather than covered?
  • Whether primer will be used where the manufacturer specifies it
  • Will RAMS and insurance details be available?

How to choose a sealant contractor

FAQs: Crookham

Is Crookham too small for you to travel to?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.

Can you work at a site such as Colthrop Industrial Estate, by Crookham?

Yes, sites like Colthrop Industrial Estate are within our area, along with the rest of Crookham. Photos and a short description are enough for a first look.

What about access for upper-floor joints?

It depends on the building. How upper joints are reached is agreed before work is booked so the fixed quote reflects it.

Do you work for managing agents and housing associations?

Yes, block and estate work is a core part of what we do. We work through buildings in a planned order with dates agreed in advance.

How long does a typical visit take?

It depends on the scope, though a typical visit usually 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.

Can you send RAMS and CSCS details before starting?

Our credentials include CHAS, Constructionline and public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

On site: what to expect

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Jobs in and around smaller places like Crookham are normally planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. We check the asbestos register for older buildings and look at the joints.
  2. A fixed quote covers the joints, products and order of work.
  3. We strip out the old sealant.
  4. The joints are prepared and resealed with the right product.
  5. Buildings are completed in turn.

Preparing the site

  • Confirm the product named in the specification
  • Tell us which areas need to stay in use
  • Make sure the joints can be reached

Ask for a quote

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

Why deal with it now?

Leaving failed external joints lets water reach the structure behind. That can lead to damp, staining and damage to finishes, which is harder to deal with than resealing. For buildings around smaller places like Crookham, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.
