Mastic sealing across Newtown
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
What the job involves on each surface
Planned maintenance
Planned resealing replaces emergency callouts and keeps budgets predictable.
Window and door perimeters on blocks
On most blocks, the frame-to-wall joint is where failure shows first. Old perimeter mastic is removed, the joint prepared and new sealant tooled in.
How we handle mastic sealing in Newtown
Managing agents and housing associations usually need paperwork before anyone starts. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We’re a Constructionline member and CHAS accredited, and we carry public liability insurance. We work on external wall and movement joints, shopfronts below residential blocks and window and door perimeters on blocks, and the usual reasons a site gets in touch are occupiers reporting cold air round windows and no planned programme for sealant. Whoever orders the work in Newtown, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
For landlords and associations with stock in and around Newtown, grouping buildings into one visit saves travel. One quote can cover a whole list of addresses.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

What affects the price in Newtown
To price the job, we consider:
- Travel to remote or island sites
- Induction, permit and paperwork requirements
- Working within restricted access windows
- Access and working height
Pricing mastic joints depends on quantities, condition and access. Call for a quote.
Sending details for a quote
However big the job, these details speed things up:
- The type of building and who uses it
- A wide shot and a close-up of the area
- Asbestos survey details if the building is older
- Anything awkward about access or site hours
To get a fixed quote, call the office on 01277 525 020 or send photos by email. You can also send details through our quote form.
Keeping the joints sound
Regular inspection catches problems early. In particular:
- Have the asbestos survey to hand for older buildings
- Make mastic part of routine maintenance checks
- Encourage occupiers to report problems at frames
- Reduce knocks to communal area joints
Our workmanship is covered for 12 months, so report any failure in that time. After that, regular inspection keeps the programme on track.
The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing.

Work for main contractors and building owners
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.
What happens if it’s left?
Open external joints let water into walls and around frames. That can lead to damp, staining and damage to finishes and those cost far more to put right. For buildings in places like Newtown, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.
The price depends on the quantity of joints, how much old material needs removing and the access. Call for a quote when you’re ready.

Frames, entrances and external joints in Newtown
The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first. Central London is about 37 miles from Newtown. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres.
For owners of several units at places like Suttons Business Park, which lies north-east of Newtown, one programme can deal with frame and external mastic across the lot. Churches, halls and community buildings such as St John and St Stephen are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. If your remit includes a building such as New Town Primary School, frame and door mastic can be programmed for the holidays.

How a job runs
Site rules come first: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. If neighbouring businesses or buildings around Newtown need work too, visits can be combined. Tell us your site hours and we’ll plan around them.
- We inspect each building and record the joints that have failed.
- 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.
- Each building is checked and signed off with the 12-month guarantee.
Before we start on site
- Point out parking and an unloading spot
- Move anything stored against the joints
- Have the specification and drawings to hand
Request a quote
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.
Advice
Newtown: questions and answers
Can you work at a site such as Suttons Business Park, by Newtown?
Yes, sites like Suttons Business Park are within our area, along with the rest of Newtown. A few photos and the unit address let us price the work.
Is Newtown off your patch?
Not at all. Newtown is within our area. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Can you quote from photos?
Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit.
What if the old mastic contains asbestos?
In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.
What paperwork can you provide?
Our credentials include CHAS, Constructionline and public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Do you work with property factors and landlords?
We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work and work can be quoted per building or as a whole.
How long do sealant joints last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
