Facade sealing near Sway
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Diagnose, treat, sign off
Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. What matters most for a job in Sway is a clear list of what needs doing, so send photos of each area. You will then get a fixed price for the work.
- We look at the joints, the drawings and the access before pricing.
- 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.
- The new sealant goes in and is tooled firmly onto both faces.
- We walk the finished joints with you before handing over.
Before we start on site
- Move anything stored against the joints
- Share the asbestos register for older buildings
- Tell us which areas need to stay in use

Advice
Facade sealing for commercial buildings in Sway
A good facade joint depends on design as much as product. The width has to suit the expected movement and the sealant’s movement capability, and closed-cell rod sets the depth, keeping the bond to two faces, often at around 2:1 width to depth, as the manufacturer advises. Most enquiries involve discoloured or dirty facade joints and weathered facade joints that have lost their grip, across shopfront frames, window and door perimeters and perimeter joints where frames meet the structure. A single leaking joint is often how a building in Sway first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Building work in places the size of Sway is usually small-scale: a handful of new houses, barn conversions, a school or hall extension. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Mastic packages on Sway sites
Sway sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team. There are a number of hotels within about 2 miles of Sway. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight.
Work at a hotel such as Forest Heath Hotel, less than half a mile south of Sway, tends to be programmed around bookings, mastic included. Extensions at sites like Lymington New Forest Hospital, 2.9 miles to the south-east of Sway, normally sit beside working departments, and the mastic follows strict access rules.
Sway is about 3 miles north-west of Lymington, in Hampshire. Looking for facade sealing in Sway? We can help, as we do across Hampshire. We work across 723 places in Hampshire. We also cover Southampton, around 13 miles from Sway.

When to call us in Sway
Three-sided adhesion is a classic installation fault. Without rod or bond-breaker tape, the bead is held back and tears as the joint moves.
Clients typically get in touch after noticing one or more of the following:
- Air leaks through failed facade joints
- Old perimeter mastic that has dried out
- Sealant pulling away from frames or panels
- Previous reseals run over old sealant
Projects at schools like St Luke's Church of England Primary School work to term dates, so mastic is programmed tightly.
Questions to ask before you book
- Their plan for phasing and protecting the area
- Health and safety accreditation such as CHAS
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Which product they’ll use, and why it suits the joint
What sets the cost
A fixed quote reflects the actual work. It takes account of:
- Whether old sealant has to be cut out first
- How accessible the joints are
- Phasing around occupants
- Joint width, depth and condition
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.
What we need to price the job
We can often quote from photographs and a few details. It helps to include:
- Whether an asbestos survey exists
- Your programme or deadline
- Photos of the joints, close up and from further back
- Approximate linear metres or a joint schedule
For a fixed quote, call the office on 01277 525 020 or use the quote form, telling us the site location and the nature of the job. Our quote form is another easy route.
Surface by surface
Precast concrete panels
Precast arrises sometimes crumble or carry old residue. Faces are cleaned to sound concrete, and damaged edges are reported before sealing.
Coping and flashing joints
Sometimes the coping or flashing itself has failed. We tell you if the fix is a roofing or metalwork job rather than a reseal.
Common questions from Sway clients
Can you work on a hospital site such as Lymington New Forest Hospital?
Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.
Is Sway too far out for you?
No. Small places get the same service as large ones. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
How long does a job like this take?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
Can the sealant be colour-matched?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Will you check whether the sealant is causing the leak?
Yes. We check the sealant joints and report what we find as part of pricing. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.

What we can’t put right
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Joints whose design needs changing by the specifier
- Render or concrete edges that have broken away
- Installing or repairing glazing systems
Not sure which it is? You can speak to us on 01277 525 020 or email the details over and we’ll tell you honestly.
Where we work in Sway
- Perimeter joints where frames meet the structure
- Cladding panel joints
- Coping and flashing joints
- Stone and brick facade joints
- Window and door perimeters
- Shopfront frames
Why act early in Sway
Leaving failed perimeter sealant also makes the eventual job bigger: wet edges break down, so repairs may be needed before resealing. Acting at the first sign of splitting keeps the fix simple. Small buildings around Sway suffer from failed joints as much as large ones. Catching it early means a reseal rather than repairs.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
