Facade sealing for commercial buildings in Wherwell Wood
Every facade quote starts with how the joints will be reached. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site, and we will fit the work around it. Site teams most often ask us about perimeter joints where frames meet the structure and facade joints cracked through the middle, on cladding panel joints, coping and flashing joints and shopfront frames.

How a job runs
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Smaller jobs around Wherwell Wood can be grouped with others nearby. A fixed quote is given before anything starts.
- First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
- The old bead is cut away completely, not overlaid.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- We walk the finished joints with you before handing over.
What we need from you
- Move anything stored against the joints
- Flag any permit to work we’ll need
- Explain the parking and delivery arrangements

Advice
New build and refits around Wherwell Wood
The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so the external programme keeps a little slack. Wherwell Wood lies roughly 63 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme.
Units on estates such as Harewood Forest Industrial Estate, 2.2 miles east of Wherwell Wood, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. Hospital estates such as Andover War Memorial Hospital (3.2 miles north-west of Wherwell Wood) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. Projects at schools like Wherwell Primary School work to term dates, so mastic is programmed tightly.

Questions about Wherwell Wood
Can you work at a site such as Harewood Forest Industrial Estate, by Wherwell Wood?
Yes. We cover Wherwell Wood and the area around it, including industrial estates, business parks and retail parks such as Harewood Forest Industrial Estate. Photos and a short description are enough for a first look.
Is hospital work, at somewhere like Andover War Memorial Hospital, something you do?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
What’s the quickest route to a quote?
There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.
What hours do you work?
Give us your site hours and any access windows in your enquiry, and we’ll plan around them. Our office runs Monday to Friday, 8am until 5pm.
Is it okay to overlay old mastic?
No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the joint cleaned back to sound material. Nothing else gives a bond that lasts.
Do you use silicone for external joints?
The product follows the joint’s movement, the surfaces and the specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing and we follow the specified product.
Can you handle several sites?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
For managing agents and facilities managers
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Wherwell Wood can form part of a wider programme across Hampshire.
What affects the price in Wherwell Wood
To price the job, we consider:
- Induction, permit and paperwork requirements
- How much there is to seal
- Location, for remote and island sites
- How accessible the joints are
A quote for facade joints depends on how many there are, their condition and the access. Call for a quote.
Before you send an enquiry
A good diagnosis starts with the right details. Tell us:
- When you need the work done
- The asbestos register, for older buildings
- Anything awkward about access or site hours
- Specification clauses that apply
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.
Keeping the joints sound
To get the most from the new sealant:
- Avoid patch repairs on failed facade joints
- Walk the elevations once or twice a year
- Keep the sealant details on the building file
- Don’t wait for a second leak before calling
After heavy weather, check vulnerable elevations for signs of water inside. Catching a new leak early keeps the repair small.
Building facade joints into a maintenance cycle avoids emergency repairs. Inspect regularly and reseal sections as they start to fail.
Leave it or put it right?
Every shower drives water through a split perimeter bead. Behind the frame, that can mean damp plaster, stained ceilings, corroded fixings and damaged insulation. Resealing now costs less than repairing interiors later. For buildings around smaller places like Wherwell Wood, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
