About our construction mastic in Marchwood
A typical mastic package covers more than window perimeters: frame perimeters inside and out, caulking to trims and boards where the specification calls for it, sanitary silicone, kitchens, and the final snag list. One contractor for all of it keeps the responsibility in one place and gives you a consistent finish across the job. We work on internal decorators’ caulk, brick and block movement joints and sanitary and kitchen joints, and the failures we’re asked to look at most are frame gaps too wide for sealant alone and inconsistent sealant finishes from plot to plot. Most enquiries from Marchwood start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
In a smaller place such as Marchwood, construction tends to mean small housing schemes, conversions and extensions to community buildings. Even a small site needs its perimeter and facade joints sized, backed and sealed properly.
Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

- 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.

- Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.

Marchwood: questions and answers
Does your area include sites such as Marchwood Industrial Park, near Marchwood?
Yes. We cover Marchwood and the area around it, including industrial estates, business parks and retail parks such as Marchwood Industrial Park. To start, just speak to us on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Would you work within a site like Priory 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.
When is resealing likely to be due?
Nobody can honestly give a figure in years, 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.
What does a mastic package usually include?
It depends on the specification, but frames, sanitary, kitchens, caulk where specified and snagging are typical.
Is Marchwood in your area?
Yes. We cover Marchwood and the rest of Hampshire. To discuss a job, give us a call on 01277 525 020 or email a schedule or drawings.
Do you use the sealant named in the specification?
Specification first, then the maker’s instructions. Preparation, backing and depth follow the product guidance.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure.
When it isn’t the sealant
Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:
- Damage to finishes by other trades after we have sealed
- Designing joint widths or choosing the specification (that sits with the designer)
- Deciding which fire-stopping product a penetration needs
If you’re not sure, just phone 01277 525 020 or send details through our quote form and we will give you a straight answer.

How the job changes by surface
External facade and movement joints
External movement joints often need primer, depending on the substrate. We prime where the manufacturer specifies.
Bathrooms, en suites and washrooms
In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Each joint is prepared, sealed and finished with a neat tooled line.
Signs you need construction mastic in Marchwood
Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A general-purpose silicone on a facade or a caulk in a wet area won’t perform like the specified product. We use what’s specified, and any substitute goes to you for acceptance.
Things that normally lead to an enquiry:
- Oversized or tapered gaps around new frames
- Frame perimeters left unsealed or poorly sealed
- A long mastic snag list close to completion
- Early adhesion failures on new external joints
New units and refits on sites such as Marchwood Industrial Park, 0.7 miles to the north-east of Marchwood, need their panel and perimeter joints sealed to the specification.

- Whether old or failed sealant will be cut out, not overlaid
Contractors’ notes for Marchwood
Marchwood is within about 1 mile of the coast. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, so we check the specified product suits the exposure before the first bead. Marchwood is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so external mastic is timed for workable conditions and agreed with the site manager.
For contractors at a school such as Marchwood Junior School, sealing has to be finished before term starts. On a healthcare site such as Priory Hospital, which lies south of Marchwood, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

When to bring in a specialist
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
