Mastic sealing across Lower Upham
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Keeping the joints sound
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Group repairs into a planned programme
- Make mastic part of routine maintenance checks
- Share your contractor requirements early
- Protect low-level joints in entrances
Ask residents or tenants to report draughts or leaks round windows early. Early reports catch failures before damage spreads.
One failed perimeter normally means others on the same building are close so a single failure is a sign to check the rest. A planned reseal saves repeated visits.
About our mastic sealing in Lower Upham
On a residential block, the work happens around people’s lives. The sequence, the areas and the dates are settled with you, giving you what you need to notify residents. Entrances and stairwells are kept in use throughout. We work on communal entrances and stairwells, window and door perimeters on blocks and balcony and threshold joints, and the usual reasons a site gets in touch are leaks at window and door perimeters and mastic failing across several blocks on an estate. One point of contact handles commercial sealant work in Lower Upham from the first photos to the final walk-round, for single jobs and planned programmes alike.
Rural conversions near places like Lower Upham often set modern frames into older stone, flint or brick. Perimeter mastic there has to grip an uneven face and suit the building’s character.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

When to call us in Lower Upham
Topping up old mastic is a common shortcut. New silicone has nothing to grip on old silicone and the repair soon fails.
Clients usually get in touch after noticing something like this:
- Window mastic that has split and shrunk
- Damp patches beside frames
- Movement joints with sealant missing
- A mix of products and colours from past repairs
Schools and community buildings such as Upham Church of England Aided Primary School need frame and external mastic kept sound like any building.
What your quote should include
- Will CSCS-carded applicators be on site?
- Will RAMS and insurance details be available?
- Health and safety accreditation such as CHAS
- How the existing material will be dealt with
Why it’s worth doing now in Lower Upham
Mixed repairs by different contractors leave a patchwork of products and colours. A block-wide reseal gives one product, one colour and one guarantee. Older rural buildings around Lower Upham move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Why clients in Lower Upham choose us
- Specification-led, product-correct work
- CHAS accredited
- Constructionline member for supplier checks
- One phone line for London, the South East and Scotland

Sending details for a quote
It doesn’t need to be a full survey. A few details are enough to get going:
- Where the site is, with the postcode
- Access details, including height
- Asbestos survey details if the building is older
- Your programme or deadline
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.
Our process
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes anything from a day to a few weeks, depending on the number of buildings and joints, and our waste is bagged and taken away as we go. For work around Lower Upham, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- A building-by-building inspection lists the failed joints.
- The quote is fixed and split as suits you.
- We agree the programme and dates with you.
- Old mastic is removed and the joint faces prepared.
- New sealant goes in with backing rod and primer where needed.
- We check the finished work and confirm the guarantee.
Getting the site ready
- Send any specification or drawings in advance
- Share your working hours and any access restrictions
- Tell us what induction or permit system the site runs

Mastic sealing in Lower Upham: the local picture
Lower Upham lies roughly 62 miles out from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres. Lower Upham sits in one of the drier corners of the country, the South East. Outside mastic still needs a dry joint and the right temperature, and the sunniest, most exposed sides of a building normally need attention first.
Churches, halls and community buildings such as Church of St Mary are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Landlords with units on estates such as Deer Park Farm Industrial Estate (1.6 miles south-west of Lower Upham) can bring frame, door and external mastic across several units into one programme.

Your questions answered
Do you work for managing agents with blocks near Hedge End station?
Yes, and several blocks can go on one quote. Send the address, photos of the elevations and your access arrangements, and we will give a fixed quote.
Is Lower Upham off your patch?
No. Places such as Lower Upham are covered as much as the big towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Is asbestos a concern with old mastic?
In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts and suspect material is tested first.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and we’ll price the work to it.
What guarantee do you give on resealing?
A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.
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.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
