Mastic sealing for businesses in Fair Cross

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Surface by surface

External movement joints

Joint size and product are matched to the expected movement with the width-to-depth ratio set as the manufacturer advises.

Commercial and mixed-use buildings

Tenants in commercial buildings need to keep trading, so we plan around them.

Mastic sealing in Fair Cross, done properly

We diagnose before we prescribe: what has failed, what caused it and whether new sealant will actually solve it. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in and backing rod used wherever a joint is deep. Most enquiries involve open joints in brickwork or panels and brittle perimeter mastic across a building, on communal kitchens and washrooms, shopfronts below residential blocks and communal entrances and stairwells. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Fair Cross, preparation and product choice get the time they need.

For owners with a single building near Fair Cross, we plan to finish in one visit where possible. Send photos of the frames and joints and we’ll give a fixed quote.

Our workmanship is guaranteed for 12 months, in Fair Cross as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Honest limits

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Water coming in from the roof or rainwater goods
  • Materials that need asbestos testing before work
  • Frames that are rotten, warped or broken

If in doubt, give us a call on 01277 525 020 or email a schedule or drawings and we’ll say what we think.

Where we work in Fair Cross

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

Common problems we fix in Fair Cross

Communal entrances and corridors see a lot of wear, and low-level joints get damaged. Regular cleaning wears them further.

Common reasons buildings call us in:

  • Window mastic that has split and shrunk
  • Draughts at frames across a block
  • Patchy repairs in mismatched sealant
  • Mastic failing across several blocks on an estate

Historic properties like Stratfield Saye House (to the south of Fair Cross) show the age of some local stock, where frame mastic must suit soft brick or stone.

Before you book anyone

  • Whether primer will be used where the manufacturer specifies it
  • What site paperwork they can supply
  • Their plan for phasing and protecting the area
  • Will failed sealant be removed rather than covered?

Our contractor checklist

Mastic sealing in Fair Cross: the local picture

Fair Cross is in the South East, one of the UK’s drier regions. Outside work still depends on dry joints, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first. Central London is about 40 miles from Fair Cross. 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.

Blocks of flats and mixed-use buildings often cluster around stations such as Mortimer station, 1.7 miles north-west of Fair Cross, and their window and balcony mastic tends to age at the same rate across a building. For owners of several units at places like Riseley Business Park, 1.7 miles to the east of Fair Cross, one programme can deal with frame and external mastic across the lot.

Fair Cross is about 6 miles east of Tadley, in Hampshire. Across the RG7 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. 723 places across Hampshire fall within our area, including Fair Cross. Sites around Reading have their own page, about 6 miles away.

Work on mastic joints is covered throughout RG7, for business premises of every kind. We also cover Stratfield Saye (1 mile south-west), West End Green (2 miles west), Stratfield Mortimer (2 miles north-west), Spanish Green (2 miles south) and Wokefield (3 miles north-west) for mastic joints. Further afield, our area takes in Basingstoke (8 miles south-west), Farnborough (11 miles south-east), Fleet (9 miles south-east), Aldershot (13 miles south-east), Alton (15 miles south) and Yateley (7 miles east).

Local landmarks in Fair Cross

Fair Cross’s nearest station is Mortimer station, roughly 1.7 miles north-west. Nearby you will also find Beaumys Castle (1.5 miles north-east). Not far away are The Marshes Local Nature Reserve and Longwater.

Site staff or a sealant specialist?

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

After the work

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Check the asbestos register before any old mastic is disturbed
  • Plan resealing building by building rather than complaint by complaint
  • Protect low-level joints in entrances
  • List the paperwork your organisation requires when you send details

If paintable sealant was used, decoration can follow once it has cured. Silicone usually can’t be painted, so keep decorators off it.

Planned resealing is easier to budget than emergency repairs. We can quote buildings in priority order so spending is spread.

Diagnose, treat, sign off

Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Jobs in and around smaller places like Fair Cross are normally planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  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. We finish each building before moving to the next.

What we need from you

  • Share the asbestos register for older buildings
  • Explain the parking and delivery arrangements
  • Share your working hours and any access restrictions

Your questions answered

Is Fair Cross too small for you to travel to?

No. Places such as Fair Cross are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Can you work at a site such as Riseley Business Park, by Fair Cross?

Yes. Estates, retail parks and business parks around Fair Cross, Riseley Business Park among them, are all within reach. To start, just speak to us on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.

Do you supply RAMS and insurance details?

Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.

When is resealing likely to be due?

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.

How many days will you need on site?

We plan the time on site around your programme and access. You will have an expected duration with the quote.

What will the job cost?

We don’t publish prices, because every site is different. Send photographs or drawings and we will price it at a fixed figure.

Will you just go over the old sealant?

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