Construction mastic for commercial buildings in Dunsden Green
The specification and the programme set the job, not to habit. Where the specification names a product, we use it; any alternative we suggest is put to you before anything changes. Joint widths, backing, primers and tooling follow the manufacturer’s guidance so the detail on the drawing is what ends up on site. The enquiries we see most involve sealant knocked or painted over by other trades and old sealant on a refurbishment that needs stripping before new work, across internal decorators’ caulk, window and door perimeters and sanitary and kitchen joints. A specialist sealant contractor works differently from a general builder: on jobs in Dunsden Green, preparation and product choice get the time they need.
Around smaller places like Dunsden Green, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, give us a call on 01277 525 020 or email the details over and we will arrange a return visit.

Questions about Dunsden Green
Is hospital work, at somewhere like Royal Berkshire Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can you work at a site such as Suttons Business Park, by Dunsden Green?
Yes. Estates, retail parks and business parks around Dunsden Green, Suttons Business Park among them, are all within reach. A few photos and the unit address let us price the work.
Are you insured?
Yes. We’re fully insured, and the certificate can go with your quote.
What accreditations do you hold?
Our applicators are CSCS-carded, and we hold CHAS accreditation and Constructionline membership. Tell us what site paperwork you need and we will confirm with the quote.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Can you come in just for snagging?
Yes. We clear snags by redoing joints rather than patching them, working to your handover date.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
Diagnose, treat, sign off
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. If others near Dunsden Green need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

Mastic packages on Dunsden Green sites
The area within 2 miles of Dunsden Green holds a number of hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. Dunsden Green sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager.
On a healthcare site such as Royal Berkshire Hospital, which lies south of Dunsden Green, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. Hotel extensions and refits, at places such as The Great House Hotel (1.5 miles south-east of Dunsden Green), typically run between busy periods, so the sealing is squeezed into short windows.
Dunsden Green is about 1 mile north-east of Caversham, in Oxfordshire. Commercial clients in Dunsden Green use us for work on mastic packages, as part of our coverage of Oxfordshire. Dunsden Green is one of 423 places we cover in Oxfordshire for mastic packages.

When it isn’t the sealant
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Frame gaps too wide for sealant, which the installer needs to correct
- Designing joint widths or choosing the specification (that sits with the designer)
- Defective windows, doors or glazing units (the supplier or installer’s job)
If you are not sure, just call the office on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.

Do you need construction mastic in Dunsden Green?
On a live site, contamination is the biggest threat to a new joint. Dust, film adhesive, damp and grease on the joint faces prevent a proper bond, so preparation matters as much here as on a reseal.
Things that typically lead to an enquiry:
- Perimeter gaps outside the sealant’s range
- Inconsistent sealant finishes from plot to plot
- Bath and shower joints scraped during the final clean
- Window and door perimeters that won’t pass inspection
On a campus such as University of Reading, 0.7 miles east of Dunsden Green, new teaching buildings and residences are usually built and refurbished around the academic year.
What your quote should include
- Which product they’ll use, and why it suits the joint
- Health and safety accreditation such as CHAS
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Will failed sealant be removed rather than covered?
Doing it in-house
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Redoing a failed joint normally costs more than getting it right at the outset, 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.

Looking after the joints
A few simple habits keep the new joints working:
- Don’t force external sealing on a damp or frosty day
- Get the mastic subcontractor involved early in the programme
- Note which sealant went where at handover
- Ask cleaners to use soft cloths around fresh sealant
At handover, keep the product details with the O&M information. That helps the building owner maintain the joints later. We can confirm the handover information you need when we quote.
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, and a delay to handover. Checking perimeters before internal finishes go on avoids it.
