Contractors’ notes for Andover Down
The area within 2 miles of Andover Down holds several hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. Andover Down sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team.
When units on a site such as Walworth Business Park (0.9 miles west of Andover Down) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. Work at a hotel such as Best Western Andover Hotel, 1.5 miles south-west of Andover Down, tends to be programmed around bookings, mastic included.

Facade sealing for commercial buildings in Andover Down
External sealing depends on the weather more than most trades. Joints have to be dry and the air and surface temperature within the product’s range, and cold, damp starts can delay work. We build that into the programme and tell you if the forecast changes the plan. We work on window and door perimeters, shopfront frames and coping and flashing joints, and the failures we’re asked to look at most are air leaks through failed facade joints and previous reseals run over old sealant. For commercial sealant work in Andover Down, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Construction in and around smaller places such as Andover Down is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Our process
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Rural sites near Andover Down may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- Photos, drawings or a visit tell us about the joints and the access.
- Product choice follows the joint’s movement and substrate.
- The existing bead comes out in full and both faces cleaned back.
- Primer is applied where the maker specifies it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- The finished joints are checked with you.
What we need from you
- Let us know about inductions and permits
- Send your site hours and access windows
- Agree which areas must stay open

Advice
Owners, agents and contractors
Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so the building keeps working while we do.
CHAS accredited and a Constructionline member, we’re straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.
When to bring in a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
What sealant work can’t fix
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Damaged frames that need replacing
- Specialist high-level access methods
- Leaks from roofs, gutters or failed flashings rather than sealant joints
If in doubt, ring 01277 525 020 or send photos by email and we will say what we think before you book.
Joints and surfaces we work on
- Stone and brick facade joints
- Coping and flashing joints
- Window and door perimeters
- Perimeter joints where frames meet the structure
- Shopfront frames
- Cladding panel joints
Why deal with it now?
If access is already up for other work, resealing at the same time makes sense. Coordinating facade sealing with other external works avoids paying for access twice. One visit to deal with every failing joint makes more sense than several trips to a place like Andover Down. Photos of every joint help us quote for the whole job.
There’s no price list, since every building and every scope is different. Call for a quote.

Questions about Andover Down
Would you work within a site like Andover Hospital (Grounds)?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can you work at a site such as Walworth Business Park, by Andover Down?
Yes. Our area takes in Andover Down and its surroundings, with estates and business parks such as Walworth Business Park included. A few photos and the unit address let us price the work.
Do you offer coloured sealant?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
What do you charge?
Every job gets its own fixed quote. For yours, call the office on 01277 525 020 or email the details over with a description of the work.
Do you need to see the site first?
It depends on the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.
What’s the quickest route to a quote?
You can use the quote form on this site; alternatively, ring 01277 525 020 or email drawings and photos. Photos, drawings or a joint schedule help us quote quickly.
Do you run new sealant over the existing bead?
No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the faces are cleaned before resealing. That is what makes the new joint last.
Signs you need facade sealing in Andover Down
Product choice matters: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Neutral-cure, facade-grade products are what most external joints need.
Common reasons buildings call us in:
- Gaps between rainscreen or cladding panels
- Leaks at window and door perimeters
- Weathered joints at frame-to-structure perimeters
- Air leaks through failed facade joints
Projects at schools like Pilgrims' Cross CofE Aided Primary School work to term dates, so mastic is programmed tightly.
