Mastic sealing for commercial buildings in Ashton
Blocks are lived in, so access and disruption have to be thought through. 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 while we work. If you’re dealing with damp patches beside frames and damaged joints in communal entrances and corridors, we can help, on communal entrances and stairwells, balcony and threshold joints and communal kitchens and washrooms alike. One point of contact handles commercial sealant work in Ashton from the first photographs to the final walk-round, for single jobs and planned programmes alike.
In and around smaller places like Ashton, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.
A 12-month guarantee applies to all our work. If an installation problem shows up, call 01277 525 020 or email the details over and we’ll arrange a return visit.

Signs you need mastic sealing in Ashton
Topping up old mastic is a common shortcut. New silicone has nothing to grip on old silicone and the repair soon fails.
Common reasons buildings call us in:
- Communal area joints that look neglected
- Occupiers reporting cold air round windows
- Mastic failing across several blocks on an estate
- Complaints coming in block by block
Landlords with units on estates such as Swanmore Business Park (2.2 miles south-east of Ashton) can bring frame, door and external mastic across several units into one programme.
Before you book anyone
- How joint depth will be controlled
- Who will actually carry out the work
- Whether old or failed sealant will be cut out, not overlaid
- Their public liability cover
When something else is needed
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Leaks through the frame itself rather than the perimeter
- Substrate edges that need repairing first
- Misted or failed double-glazed units
Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we will tell you honestly before you book.
What we seal
- Window and door perimeters on blocks
- Balcony and threshold joints
- Shopfronts below residential blocks
- External wall and movement joints
- Communal kitchens and washrooms
- Communal entrances and stairwells
How the quote is worked out
We price every job individually. The main factors are:
- How accessible the joints are
- Site requirements such as inductions and permits
- Working within restricted access windows
- Which sealant the job calls for
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.
Details that help us quote
We can often quote from photographs and a few details. It helps to include:
- Rough lengths or quantities, or drawings if you have them
- Any dates the work must fit around
- The product your specification calls for
- Anything awkward about access or site hours
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, give us a call on 01277 525 020 or email drawings and photos.
Blocks and managed buildings in Ashton
Ashton lies roughly 61 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations; their frame mastic often ages block-wide. Ashton sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, while the elevations that take the most sun tend to show hardened mastic first.
Trustees of buildings like Church of St Peter can bring frame and external mastic into a planned maintenance list. Site managers at schools like Bishops Waltham Infant School can fit frame mastic into the summer works.
Ashton is about 5 miles north-east of Hedge End, in Hampshire. Our applicators travel to Ashton for work on mastic joints. Ashton is one of 723 places in Hampshire on our list. We also cover Southampton, around 8 miles from Ashton.
Business premises anywhere in SO32 are within our area. We also cover Upham (1 mile north-west), Bishop's Waltham (1 mile south), Durley Street (1 mile south-west), Lower Upham (1 mile west) and Wintershill (2 miles west). A short drive away, we cover Winchester (8 miles north-west), Gosport (12 miles south), Havant (13 miles south-east), Eastleigh (5 miles west), Fareham (8 miles south) and Horndean (10 miles south-east).
Around Ashton
In Ashton, that means premises near Swanmore College of Technology, among other places. Ashton’s nearest station is Botley station, about 4 miles south-west of the centre. Nearby you will also find Bishop's Waltham Museum (1.1 miles south) and Moorgreen Hospital (5.3 miles south-west). The countryside around Ashton includes Beacon Hill and Bishops Waltham Branch LNR.
Site staff or a sealant specialist?
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Looking after the joints
To get the most from the new sealant:
- Track which buildings were done and when
- Start inspections with the most exposed faces
- Encourage occupiers to report problems at frames
- Keep bins and bikes away from communal door frames
Where a paintable product was specified, it can be painted after curing. Non-paintable silicone shouldn’t be painted over unless told otherwise.
The longer failed joints are left, the more likely the substrate edges break up. Then the edges may need repairing first and the job grows.

Ashton: questions and answers
Can you quote for a block close to Botley station?
Yes, and several blocks can go on one quote. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.
Will you take on work at estates like Swanmore Business Park, close to Ashton?
Yes. We cover Ashton and the area around it, including industrial estates, business parks and retail parks such as Swanmore Business Park. To start, just give us a call on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
How many days will you need on site?
The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.
Do you cover Ashton?
Yes. We take on work across Ashton, and the same phone number covers every area.
How do you reach windows on upper floors?
Every block is different. We agree access with you at quote stage so the fixed quote reflects it.
What if the old mastic contains asbestos?
Some mastics in pre-2000 buildings contain asbestos. We check the asbestos register or survey before disturbing it, and if it’s suspected, work stops until it’s tested.
How a job runs
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before the next one starts.
