Do you need facade sealing in Lower Slackstead?
New sealant run over old sealant rarely holds. Cured silicone won’t accept a new silicone bead, and the patch soon lifts.
Clients typically get in touch after noticing something like this:
- Weathered joints at frame-to-structure perimeters
- New sealant peeling off old mastic
- Discoloured or dirty facade joints
- Air leaks through failed facade joints
With historic properties like Mottisfont Abbey, 4.3 miles west of Lower Slackstead, in the area, refurbishment work often meets old masonry that needs compatible sealants.
Questions to ask before you book
- Whether old or failed sealant will be cut out, not overlaid
- How they’ll work around occupants
- Are they CHAS accredited or on Constructionline?
- Will CSCS-carded applicators be on site?

We seal window and door perimeters, cladding panel joints, external facade joints and perimeter joints where frames meet the structure on offices, blocks and industrial units.

Leave it or put it right?
Each spell of rain drives water past a failed facade joint. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing early costs far less than repairing what the water reaches. Older rural buildings around Lower Slackstead move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
The product called for affects the cost, and so does the preparation. Access, phasing and site rules also count.
What you get with us
- A Constructionline member, so easy to vet
- Public liability insurance in place
- Coloured sealants to suit the setting, where available
- Work to your specification and the manufacturer’s guidance

Contractors’ notes for Lower Slackstead
The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack. Lower Slackstead lies roughly 67 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme.
Hospital estates such as Romsey Community Hospital, 3 miles south-west of Lower Slackstead, 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. For contractors refurbishing units at places like Sleepy Hollow Business Park, 1.2 miles south of Lower Slackstead, the mastic covers cladding panels, roller-door and window perimeters.

Our process
On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself usually taking a day or two for a few elevations, and longer where access has to be moved around the building. For a building around Lower Slackstead, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- First we review photos, 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.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- The new sealant goes in and is tooled firmly onto both faces.
- We walk the finished joints with you before handing over.
Getting the site ready
- Tell us your opening times and when work is allowed
- Arrange parking or a loading space
- Send asbestos survey details if the building is pre-2000

Related advice
Site staff or a sealant specialist?
Some joints are best left to specialists: 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.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Maintenance after handover
Problems stay small when the joints are checked regularly. Specifically:
- Confirm the survey covers external sealants in older buildings
- Never let anyone seal over old sealant
- Avoid harsh cleaners on facade sealant
- Note when each elevation was last resealed
Following storms, look inside for damp or staining near frames. An early report typically means a small reseal rather than a bigger repair.
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.
Your questions answered
Do you take on work at healthcare sites like Romsey Community Hospital?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Is a smaller place like Lower Slackstead outside your area?
No. Places such as Lower Slackstead are covered as much as the big towns. 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.
Do you replace failed glazing units?
No. A glazing contractor handles that. We reseal window perimeters, panel joints and frame-to-structure perimeters across the facade.
Will you quote for a small job?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
How long do sealant joints last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Do you hold CHAS accreditation?
Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
What sealant work can’t fix
We check first that sealant really is the fix. It won’t put right:
- Joints whose design needs changing by the specifier
- Installing or repairing glazing systems
- Water getting in through cracked render or porous masonry
