Aftercare for building managers
After handover, these steps help:
- Check that rainwater leaves the facade the way it was designed to
- Note when each elevation was last resealed
- Check the asbestos register before old mastic is disturbed
- Avoid patch repairs on failed facade joints
Keep gutters, sills and drainage paths clear. Good drainage keeps water moving off the facade rather than sitting against the joints.
Get the joint design right when resealing: correct depth, proper backing and a sealant that can take the movement. A well-designed joint lasts longer than a like-for-like copy of a failed one.
Facade sealing in Picket Twenty, done properly
Facade joints are the line of defence between the weather and the building fabric. Once a perimeter seal fails, water tracks in around frames and panels. We cut out failed facade joints and reseal them with a facade-grade sealant suited to the movement. If you have unsightly perimeter sealant on a visible elevation and old perimeter mastic that has dried out, we can help, whatever the surface. A specialist sealant contractor works differently from a general builder: on jobs in Picket Twenty, preparation and product choice get the time they need.
Construction in and around smaller places such as Picket Twenty is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

What sealant work can’t fix
We check first that sealant really is the fix. It won’t put right:
- Work on the window or framing system itself
- Joints whose design needs changing by the specifier
- Cracked or spalling substrates that need repair before sealing
Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we will tell you honestly before you book.
What we seal
- Cladding panel joints
- Window and door perimeters
- Coping and flashing joints
- Shopfront frames
- Stone and brick facade joints
- Perimeter joints where frames meet the structure
Common problems we fix in Picket Twenty
When the sealant tears down its centre, it has usually been asked to move more than it can. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.
These are often picked up first by site or facilities staff:
- Perimeter sealant that has split or peeled away
- Failed sealant on precast panel joints
- Failed seals around shopfront and entrance frames
- Water coming in around window frames
When units on a site such as Walworth Business Park, 0.6 miles to the north of Picket Twenty, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Site staff or a sealant specialist?
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
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.
FAQs: Picket Twenty
Can you take on a job at a hospital such as Andover Hospital (Grounds)?
Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.
Is Walworth Business Park, near Picket Twenty, within your area?
Yes. We cover Picket Twenty and the area around it, including industrial estates, business parks and retail parks such as Walworth Business Park. A few photographs and the unit address let us price the work.
Is colour matching possible?
It depends on the product specified. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.
When can the area be used after sealing?
We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Can staff carry on working while you’re here?
Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.
