How we handle construction mastic in Brockenhurst
Perimeter sealing outside needs a dry joint and the right temperature. Cold or damp mornings, frost and condensation on frames can all hold external sealing up so it helps to sequence elevations with some flexibility. Internal sealing often fills those days. Most enquiries involve cracks opening in caulked internal joints and bath and shower joints scraped during the final clean, across sanitary and kitchen joints, cladding and panel joints and brick and block movement joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Brockenhurst it comes down to the same thing: the right product in a properly prepared joint.
Around places like Brockenhurst, a lot of construction is the conversion of older buildings, which leaves joints between old walls and new frames that need a sealant able to take the movement, in a colour the planners or architect are happy with.
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 spell out the cover before we begin.

Owners, agents and contractors
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.
On site: what to expect
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. If neighbouring businesses or buildings around Brockenhurst need work too, visits can be combined. Tell us your site hours and we’ll plan around them.
- We walk the site or review drawings to understand the package.
- You receive a fixed quote covering scope, products and sequence.
- Paperwork is agreed and applicators are inducted on site.
- We seal plot by plot or floor by floor in line with the programme.
- Any frame gaps or issues outside our scope are flagged to the site team.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
Before we start on site
- Tell us which areas need to stay in use
- Move anything stored against the joints
- Send your site hours and access windows

Different surfaces, different methods
Snagging before handover
Snagging is often the final mastic stage. We can work through the snag list area by area, cutting out damaged joints and resealing them properly.
Window and door perimeters
Gaps around frames have to be within the sealant’s range. We check them during the first walk-round and flag any that need packing or adjusting before sealing starts.
What we can’t put right
Honesty saves time and money. New sealant won’t cure:
- Joints damaged after sign-off by following trades
- Designing joint widths or choosing the specification (that sits with the designer)
- Oversized gaps that need packing or adjustment by others
Not sure which it is? You can call 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.
Where we work in Brockenhurst

Aftercare for building managers
Keep the joints in good shape with a few simple steps:
- Record the products used in the O&M file
- Bring the mastic contractor in after the last trades are through
- Brief the final clean team to avoid blades near sealant
- Plan external elevations with the weather in mind
If a joint is damaged after sealing, flag it early. We can return to clear snags before handover.
Sealing outside when the joint is damp or too cold leads to poor adhesion. Waiting for a dry joint and the right temperature is better than redoing work, so we plan external work with that in mind.
Mastic packages on Brockenhurst sites
The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager. Brockenhurst has plenty of hotels close by, all within 2 miles. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
New wings at hospitals like Lymington New Forest Hospital (to the south of Brockenhurst) bring long runs of window and panel joints to seal. Projects at colleges like Brockenhurst College (to the east of Brockenhurst) tend to run to term dates, so the mastic is planned tightly.
Brockenhurst is about 5 miles north of Lymington, in Hampshire. We cover commercial sites throughout Brockenhurst, whether it’s a single job or part of a planned programme.

Common problems we fix in Brockenhurst
A new building moves while it dries and settles. Plaster, screeds, timber and blockwork all shrink as they lose moisture and internal caulk in a moving joint is usually the first to crack. Choosing the right product for each joint reduces that.
If one of these sounds familiar, it’s time for a closer look:
- External joints sealed in damp or cold conditions that are now failing
- Cracks opening in caulked internal joints
- Different trades sealing to different standards
- Perimeter gaps outside the sealant’s range
When a school such as Brockenhurst Church of England Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.

Your questions answered
Will you plan work around the academic year at somewhere like Brockenhurst College?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
