Construction mastic in Lymington
On refurbishments, the mastic package usually includes cutting out old sealant as well as sealing new work. Old beads come out completely, as fresh silicone can’t grip old. After that, the joints are prepared and sealed to the specification. If you are dealing with frame gaps too wide for sealant alone and internal caulk splitting as the building dries out, we can put it right. Facilities teams, main contractors and managing agents in Lymington tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Many towns of Lymington’s size have older buildings being converted or extended, which puts new frames and panels against old brick, stone or render. Those junctions need a sealant and primer that suit both surfaces.
Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Site staff or a sealant specialist?
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

How a job runs
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Town-centre premises in Lymington may have limited parking, so tell us what’s nearby. Industrial and business units usually have yard or car park space.
- First we take quantities off the drawings and read through the specification.
- A fixed quote sets out the scope, the products and the sequence.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- Work follows the programme, area by area, as rooms and elevations become ready.
- Joints are cleaned, primed where the maker requires it, backed and sealed to the specification.
- Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.
What we need from you
- Point out any areas we must not close
- Make sure the joints can be reached
- Warn occupants and staff about the work

Advice
New build and refits around Lymington
Lymington is within about 1 mile of the coast. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, so joint design, primers and product choice deserve extra care. Lymington 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 we time external mastic for dry faces and agree it with the site team.
For a contractor working at a hospital such as Lymington New Forest Hospital, which lies north of Lymington, perimeter and facade sealing is planned around patients and deliveries. School extensions, at buildings such as Lymington Junior School, normally run to the summer holidays, mastic included. For a contractor at a hotel such as Londesborough Hotel (less than half a mile east of Lymington), the mastic often has to be finished before a reopening date.

What the job involves on each surface
Kitchens and utility areas
Worktop upstands, sinks and splashbacks are sealed once the kitchen is fitted. A kitchen-suitable sealant is used and hygienic or food-safe grades wherever food contact is possible.
Fire-rated sealant where specified
Fire-rated sealant forms part of some packages, installed to the product’s tested detail where it is specified. Fire stopping design belongs to the designer and building control and we install what’s specified.
Common questions from Lymington clients
Can the mastic package for our job in Lymington follow the site programme?
Yes. Send the programme and drawings, and we’ll plan the mastic to suit the stages. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Does a coastal location like Lymington affect which sealant is used?
It can. Coastal exposure works external joints harder than inland weather. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
What about RAMS and site documents?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
How long do sealant joints last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Can you quote from photos?
It depends on the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs normally get a visit.
Can you work to our specification?
Yes. Send it with your enquiry, and we will price the work to it, flagging anything that needs clarifying.
Can staff carry on working while you are here?
Yes, as long as we plan it. Tell us your site hours and access windows and we’ll plan around them.
What happens if it’s left?
Leaving mastic to whichever trade is fitting the element can look cheaper on paper. The result tends to be uneven finishes and arguments about who should seal what. A single mastic package gives one point of responsibility and a consistent finish. In Lymington, as anywhere, the simplest time to fix a failed joint is before it leaks. After a leak, there’s drying, repairs and redecoration on top.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Aftercare for building managers
Cleaning and maintenance staff play a part too. Pass these on to them:
- Don’t force external sealing on a damp or frosty day
- Protect sealed areas from following trades
- Ask installers to correct oversized gaps first
- Note which sealant went where at handover
Record which products went where in the handover file. Future maintenance is easier when the products are known, and tells you what to reseal with. Tell us what records you need and we will confirm with the quote.
Oversized gaps are a problem better caught early. Filling a wide gap with sealant alone sets up a failure, so the installer needs to correct it first. We flag them as soon as we see them.
Work for main contractors and building owners
Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
