Michelmersh: questions and answers
Can you work on a hospital site such as Romsey Community Hospital?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is Michelmersh off your patch?
Not at all. Michelmersh is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Can you just add new sealant on top?
No. New sealant won’t hold on old sealant, so the old bead is cut away. That is what makes the new joint last.
Which sealant do you use on facades?
Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others, depending on the substrate and the specification.
Should we check old sealant for asbestos?
It’s worth checking in any building from before 2000. The dutyholder holds the asbestos register, so ask for it before we start. Suspect material is left alone until it has been tested.
Who decides which product is used?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Is the work guaranteed?
Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.
About our facade sealing in Michelmersh
Some clients need every window on a block resealed; others need a few leaking frames sorted. The approach doesn’t change with the size: old sealant out, faces cleaned, depth set and a new bead tooled in. A 12-month guarantee applies to our workmanship. If you have weathered facade joints that have lost their grip and cold air coming in at window perimeters, we can help. Whether you call it commercial sealant work, mastic application or joint sealing, in Michelmersh it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Conversions of older rural buildings near smaller places such as Michelmersh bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Cost factors for facade joints
What shapes the price:
- Travel to remote or island sites
- Working within restricted access windows
- The size and state of each joint
- Whether old sealant has to be cut out first
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
Before you send an enquiry
A few photos plus some basic facts will normally do. It helps to include:
- Clear photos of the problem areas
- The asbestos register, for older buildings
- The site address and postcode
- Anything awkward about access or site hours

Why act early in Michelmersh
A few metres of new sealant compare well with replacing ceilings, linings or damaged stock. Water through a failed joint rarely stays where it starts, so the real damage is often some distance away. Around Michelmersh, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we will quote for the lot.
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

Looking after the joints
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Avoid patch repairs on failed facade joints
- Add perimeter sealant to planned maintenance checks
- Keep sills, gutters and drainage paths clear
- Plan facade sealing alongside redecoration
Look at perimeter and panel joints as part of routine building checks. Signs to look for are cracking, edges lifting, chalking and stiffness; note where they appear.
Use each reseal to correct the joint: 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.
On site: what to expect
Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. Smaller jobs around Michelmersh can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.
- Photos, drawings or a visit tell us about the joints and the access.
- We confirm the joint type, movement and the specified product.
- 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.
- We go over the completed work with you before leaving.
Getting the site ready
- For older buildings, check the asbestos register before work
- Point out any areas we must not close
- Make sure the joints can be reached

Contractors’ notes for Michelmersh
At about 69 miles from central London, Michelmersh is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme. Michelmersh 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 the external programme keeps a little slack.
Historic houses such as Mottisfont Abbey, 1.2 miles north-west of Michelmersh, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. For contractors refurbishing units at places like Yokesford Hill Industrial Estate (1.6 miles south-east of Michelmersh), the mastic covers cladding panels, roller-door and window perimeters.

- Previous reseals run over old sealant
