Mastic sealing for commercial buildings in Ashley
Owners and agents usually inherit a building’s mastic rather than choose it, and it ages quietly: it sits round windows and doors, along external joints and through communal areas. Once it cracks, hardens or comes away, draughts and water find a way in along with complaints. If you have a mix of products and colours from past repairs and occupiers reporting cold air round windows, we can put it right. Facilities teams, main contractors and managing agents in Ashley tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
In and around smaller places like Ashley, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Should maintenance staff do it?
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

What else we do in Ashley
Ashley: questions and answers
Will you price a mastic programme across our Ashley portfolio?
Yes, we quote for single buildings and for programmes across several blocks. Send the addresses and photographs and we’ll give a fixed quote.
Is Ashley too small for you to travel to?
Not at all. Ashley is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
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.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.
Do you supply RAMS and insurance details?
We are CHAS accredited, a Constructionline member and carry public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Does the weather affect the work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
What if the old mastic contains asbestos?
We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.
Surface by surface
Planned maintenance
Mastic wears out like any building component; how fast comes down to movement, weather, UV and the product. Inspecting joints regularly keeps programmes on track.
External movement joints
Brickwork, blockwork and panel joints let a building move. Failed sealant in a movement joint lets water in.
Block-wide mastic in Ashley
At about 66 miles from central London, Ashley is within reach of the capital. Within reach of London, blocks run by agents and associations are common around stations, and window and balcony mastic on them tends to age at the same rate. Ashley is in the South East, one of the UK’s drier regions. External mastic still waits for dry faces and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.
Buildings close to stations like Mottisfont & Dunbridge station, 5 miles to the south-west of Ashley, are often flats over shops, with frame mastic to keep sound. If you are responsible for a building such as St Mary's Church, frame and door mastic needs the same attention as any other property. With historic buildings such as Mottisfont Abbey (to the south-west of Ashley) in the wider area, owners of older properties around Ashley should expect mastic to need a product that suits old masonry.
Ashley is about 6 miles north of Romsey, in Hampshire. We send applicators to Ashley for mastic joints. Our Hampshire coverage takes in 723 places. Southampton is covered too, some 11 miles away.

From enquiry to sign-off
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes one or more days per building, depending on the joint lengths and the access, and our waste is bagged and taken away as we go. For work around Ashley, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- First we look at the mastic on each building and note what needs replacing.
- You get a fixed quote, priced per building where that helps your budgeting.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Completed joints are inspected and carry a 12-month workmanship guarantee.
Getting the site ready
- Tell staff and tenants when we’ll be in
- Point out any areas we must not close
- Move anything stored against the joints

Advice
What affects the price in Ashley
Quotes vary with the job. Expect it to depend on:
- Distance, for remote addresses
- The total length or number of joints
- The site’s rules and procedures
- Backing rod, priming and other preparation
Pricing mastic joints depends on quantities, condition and access, plus any specification you’re working to. Call for a quote.
What to include in your enquiry
It doesn’t need to be a full survey. These details are enough to start:
- The site address and postcode
- Anything awkward about access or site hours
- The product your specification calls for
- Whether the building will be occupied during the work
Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.
What sealant work can’t fix
Some faults sit outside our scope, and we say so rather than covering them up:
- Glazing that needs replacing
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Frames that are rotten, warped or broken
If in doubt, give us a call on 01277 525 020 or send details through our quote form and we will say what we think.

Aftercare for building managers
To get the most from the new sealant:
- Prioritise elevations facing the weather
- Avoid piecemeal callouts where you can
- Check the asbestos register before any old mastic is disturbed
- Make it easy for occupiers to report draughts
Encourage occupiers to report water or draughts at frames. Early reports catch failures before damage spreads.
Mastic fails gradually, then all at once in a wet spell. Resealing when cracking first shows avoids water damage and the complaints that come with it.
