About our mastic sealing in Martin
For blocks and buildings in Martin and across Hampshire, the process is the same: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. A list of buildings, a few photographs and approximate joint numbers are enough for a quick quote or we can visit. We work on shopfronts below residential blocks, window and door perimeters on blocks and external wall and movement joints, and what we are called in for most is window mastic that has split and shrunk and patchy repairs in mismatched sealant. A single leaking joint is often how a building in Martin 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.
Owners and agents with buildings around smaller places such as Martin tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

From enquiry to sign-off
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes a day or two for a single block, longer for an estate programme, and we clear our waste as we work. For a building around Martin, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.
- First comes a look at the joints and, for older buildings, the asbestos records.
- The products and programme are set out in a fixed quote.
- Failed mastic is removed completely.
- The joints are prepared and resealed with the right product.
- Buildings are completed in turn.
What we need from you
- For older buildings, check the asbestos register before work

Advice
How the quote is worked out
The price varies from site to site. Expect it to depend on:
- Removal of failed or old sealant
- Working within restricted access windows
- Location, for remote and island sites
- Specialist products, such as fire-rated or hygienic sealants
What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.
Before you send an enquiry
Good information means a firmer quote. When you get in touch, include:
- The site address and postcode
- Access details, including height
- Clear photographs of the problem areas
- The product your specification calls for
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
What sealant work can’t fix
We check first that sealant really is the fix. It isn’t the answer for:
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Substrate edges that need repairing first
If in doubt, ring 01277 525 020 or email a schedule or drawings and we’ll say what we think.
Joints and surfaces we work on
- Shopfronts below residential blocks
- Communal entrances and stairwells
- Balcony and threshold joints
- Window and door perimeters on blocks
- External wall and movement joints
- Communal kitchens and washrooms
Doing it in-house
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
FAQs: Martin
What paperwork can you provide for a job in Martin?
We will confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We are CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.
Can one quote cover a number of our buildings near Martin?
Yes. Portfolio-wide programmes are a regular request. We can phase the programme to suit your budgets and notice periods.
Is mastic sealing guaranteed?
Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.
How do you handle work on occupied blocks?
We plan around people living or working in the building. Dates and areas are agreed with you so residents or tenants can be told, and entrances stay in use.
Is Martin in your area?
Yes. Martin falls within our area, and you can speak to us on 01277 525 020 or use the quote form to get started.
How long does a job like this take?
That varies with the scale of the job, though a typical visit usually takes one or more days per building, depending on the joint lengths and the access. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Do you hold CHAS accreditation?
Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
Why it’s worth doing now in Martin
Piecemeal repairs over the years often leave mismatched sealant. Resealing a whole building gives a consistent finish. For buildings around smaller places like Martin, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
Why us?
- Sealing commercial buildings since 2005
- A fixed quote before work starts
- Workmanship guaranteed for 12 months
- One phone line for London, the South East and Scotland

Frames, entrances and external joints in Martin
Rainfall across the South East, Martin included, is lower than in many parts of the UK. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.
Older community buildings, Church of All Saints among them, often have frames of mixed ages whose mastic varies. For owners and agents with buildings in or around Martin, block-wide mastic programmes deal with frames and external joints of the same age together.

What else we do in Martin
Maintenance after handover
Once the work is signed off, these steps help:
- Plan resealing building by building rather than complaint by complaint
- Check sealant joints during planned building inspections
- Start inspections with the most exposed faces
- Have the asbestos survey to hand for older buildings
Keep records of when each building was resealed. That makes future programmes easier to plan and shows what was done.
Leaks at window perimeters spoil finishes and can affect frames. Early resealing is far simpler than repairs inside.
