Construction mastic in Wash Water, done properly
Refurbishment work needs a slightly different approach from new build. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone. After that, the joints are prepared and sealed to the specification. We work on sanitary and kitchen joints, brick and block movement joints and window and door perimeters, and what we’re called in for most is missed perimeter joints on a new elevation and a long mastic snag list close to completion. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Wash Water it comes down to the same thing: the right product in a properly prepared joint.
In the countryside around places like Wash Water, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Why act early in Wash Water
When a package runs over budget, downgrading the product is a common first thought. The saving is small next to the cost of callbacks and defects. Where an alternative is genuinely suitable, we’ll say so. One visit to deal with every failing joint makes more sense than several trips to a place like Wash Water. Photos of every joint help us quote for the whole job.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.

Advice

Looking after the joints
Cleaning and maintenance staff play a part too. Pass these on to them:
- Ask cleaners to use soft cloths around fresh sealant
- Don’t force external sealing on a damp or frosty day
- Don’t schedule sealing before decorators and flooring are done
- Record the products used in the O&M file
A new structure shifts as it loses construction moisture. Flexible sealants in the right joints handle normal movement. If that happens, let us know.
A missed perimeter seal on one window can wet the reveal and the plaster inside. On a new building that means remedial work after decorating. Checking perimeters before internal finishes go on avoids it.
Doing it in-house
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Can you work around term dates at a campus such as Newbury College?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Can weather delay the job?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

Construction mastic in Wash Water: the local picture
Wash Water sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager. Central London is about 55 miles from Wash Water. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme.
For a contractor working at a hospital such as West Berkshire Community Hospital, which lies north-east of Wash Water, perimeter and facade sealing is planned around patients and deliveries. With historic properties like Highclere Castle (to the south of Wash Water) in the area, refurbishment work often meets old masonry that needs compatible sealants. Units on estates such as Newbury Retail Park (to the north-east of Wash Water) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
