Mastic sealing in Crockerhill
We diagnose before we prescribe: which joints have failed, why, and whether sealant is the right answer. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed, with backing rod setting the depth where it’s needed. We work on communal kitchens and washrooms, external wall and movement joints and shopfronts below residential blocks, and what we’re called in for most is failed external movement joints and water getting in round frames after rain. Most enquiries from Crockerhill start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
For owners with a single building near Crockerhill, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Site staff or a sealant specialist?
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
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.
When something else is needed
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Leaks through the frame itself rather than the perimeter
- Glazing that needs replacing
- Roof leaks, gutters or failed flashings that aren’t sealant joints
Not sure which it is? You can speak to us on 01277 525 020 or send photos by email and we will tell you honestly before you book.

Mastic sealing around Crockerhill: what changes locally
The sea is no more than about 3 miles from Crockerhill. On buildings near the shore, the side facing the weather normally needs its mastic renewed first, so it’s worth inspecting those sides more often. Rainfall across the South East, Crockerhill included, is lower than in many parts of the UK. Outside work still depends on dry joints, while the elevations that take the most sun tend to show hardened mastic first.
Schools and community buildings such as The Henry Cort Community College need frame and external mastic kept sound like any building. Landlords with units on estates such as Knowle Village Business Park (1.2 miles west of Crockerhill) can bring frame, door and external mastic across several units into one programme. Older community buildings, Church of St Nicholas among them, often have frames of mixed ages whose mastic varies.

What else we do in Crockerhill
What affects the price in Crockerhill
The price varies from site to site. It mainly depends on:
- Phasing around occupants
- Joint width, depth and condition
- The total length or number of joints
- How much existing material needs removing
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.
Sending details for a quote
For an accurate fixed quote, we need a clear picture of the site. Useful things to include:
- Drawings or a marked-up plan, if available
- The product your specification calls for
- Whether the building will be occupied during the work
- Any dates the work must fit around
Need a figure for a tender or a budget? Send the scope and any drawings, and we’ll return a fixed quote that you can work with. For a chat about it beforehand, speak to us on 01277 525 020 or send details through our quote form.
Crockerhill: questions and answers
Is a smaller place like Crockerhill outside your area?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Do you work for managing agents with blocks near Fareham station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Send the address, photographs of the elevations and your access arrangements, and we will give a fixed quote.
Can you send RAMS and CSCS details before starting?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member.
How long does a job like this take?
That varies with the scale of the job, but the work usually takes anything from a day to a few weeks, depending on the number of buildings and joints. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Do you guarantee the mastic work?
Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.
Can you plan resealing across several buildings?
We can. We survey and price each building, then work through them in order, and the programme can start with the worst.
Can you take on resealing for a block portfolio?
We do. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords, and we quote building by building or as a programme.
Our process
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Rural sites near Crockerhill may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- A building-by-building inspection lists the failed joints.
- You get a fixed quote, per block or for the whole programme.
- We agree the programme and dates with you.
- Failed sealant is removed and the faces prepared.
- New sealant goes in with backing rod and primer where needed.
- We check the finished work and confirm the guarantee.
Preparing the site
- Tell staff and tenants when we will be in
- Let us know about inductions and permits
- Send your site hours and access windows
