Construction mastic in Rudmore
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
What sets the cost
Before we quote, we look at:
- Joint width, depth and condition
- How much there is to seal
- Access and working height
- Induction, permit and paperwork requirements
A quote for mastic packages depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.
What to include in your enquiry
To price the job accurately, we need to understand the site. Send us:
- The type of building and who uses it
- How the joints are reached, and at what height
- The product your specification calls for
- Approximate linear metres or a joint schedule
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.
About our construction mastic in Rudmore
The programme rarely stands still, so the mastic package has to flex with it. We agree a sequence at the start and adjust it as the site manager releases areas. That keeps the work right first time and saves rework. Most enquiries involve external joints sealed in damp or cold conditions that are now failing and internal caulk splitting as the building dries out, across floor and skirting junctions, window and door perimeters and cladding and panel joints. Facilities teams, main contractors and managing agents in Rudmore tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
For a contractor on a smaller site near Rudmore, one mastic visit at the right stage saves return trips. Tell us when scaffold comes down and when decoration finishes, and we will plan around those stages.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, phone 01277 525 020 or use the quote form and we will arrange a return visit.

Leave it or put it right?
It helps to bring the mastic subcontractor in before the package is urgent. Early involvement means gaps, products and access are sorted before the programme bites, which avoids last-minute problems. Called in at the end, the same issues surface during handover. Small buildings around Rudmore suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Other services in Rudmore
What we’re called out for in Rudmore
A joint without backing rod or bond-breaker often fails early. Bonded to the base of the joint and both sides, sealant can’t stretch evenly.
Any of the following is a good reason to get the joints checked over:
- Perimeter gaps outside the sealant’s range
- Caulk cracking where joints are moving more than expected
- A long mastic snag list close to completion
- Frame perimeters left unsealed or poorly sealed
On a healthcare site such as St James Hospital, 2 miles south-east of Rudmore, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
Questions to ask before you book
- Who will actually carry out the work
- Their public liability cover
- How joint depth will be controlled
- Will RAMS and insurance details be available?

FAQs: Rudmore
Will you take on work at estates like Victory Retail Park, close to Rudmore?
Yes. We cover Rudmore and the area around it, including industrial estates, business parks and retail parks such as Victory Retail Park. Send details of the unit and the work through our quote form for a quick quote.
Is Rudmore too far out for you?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.
What do you charge?
That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we’ll price it properly.
How do I request a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.
Do you take on multi-site work?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
How long do sealant joints last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Can staff carry on working while you’re here?
Yes, as long as we plan it. Tell us your site hours and access windows and we’ll plan around them.
Sites and facades in and around Rudmore
The sea is no more than about 1 mile from Rudmore. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, so joint design, primers and product choice deserve extra care. Rudmore lies roughly 64 miles out from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme.
Further education sites such as Portsmouth College (1.7 miles east of Rudmore) are extended and refurbished from time to time, with mastic often programmed into the summer break. For a contractor at a hotel such as The Avenue Hotel, 0.6 miles to the north of Rudmore, the mastic often has to be finished before a reopening date.

On site: what to expect

Advice
Keeping the joints sound
After handover, these steps help:
- Get the mastic subcontractor involved early in the programme
- Ask cleaners to use soft cloths around fresh sealant
- Note which sealant went where at handover
- Check frame gaps are within the sealant’s range before sealing
Our 12-month guarantee covers the workmanship from sign-off. Damage by others isn’t a workmanship fault, so protecting sealed areas matters.
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.
