Mastic sealing for commercial buildings in Botley
Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Our applicators are CSCS-carded and we hold public liability insurance. Resealed mastic joints in Botley carry our 12-month guarantee. We work on communal entrances and stairwells, shopfronts below residential blocks and window and door perimeters on blocks, and what we’re called in for most is draughts at frames across a block and repeated reactive repairs to the same buildings. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Botley it comes down to the same thing: the right product in a properly prepared joint.
In a smaller place such as Botley, landlords and agents tend to look after small blocks, flats over shops, sheltered housing and commercial units. Their window perimeters and external joints need renewing as the mastic ages.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

What sealant work can’t fix
Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:
- Frames that are rotten, warped or broken
- Materials that need asbestos testing before work
- Substrate edges that need repairing first
If in doubt, phone 01277 525 020 or send photos by email and we will say what we think.
Where we work in Botley
- Communal entrances and stairwells
- Shopfronts below residential blocks

For managing agents and facilities managers
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.
Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
Your questions answered
Can you quote for a block close to Botley station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Photos of each elevation help us quote accurately.
Does your area include sites such as Bottings Industrial Estate, near Botley?
Yes. Our area takes in Botley and its surroundings, with estates and business parks such as Bottings Industrial Estate included. A few photos and the unit address let us price the work.
Do you seal on top of existing sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Do you check for asbestos in old sealant?
In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.
Can you plan resealing across several buildings?
Block-wide and estate programmes are common. You get a fixed quote per building or for the whole job.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
When to call us in Botley
Occasionally the substrate fails, not the sealant for example where render or brick edges crumble. We’ll tell you if the joint edges need repairing before resealing.
Most enquiries start with one or more of the following:
- Open joints in brickwork or panels
- Patchy repairs in mismatched sealant
- Communal area joints that look neglected
- Estate-wide sealant that is simply worn out
Site managers at schools like Botley Church of England Controlled Primary School can fit frame mastic into the summer works.
What to look for in a quote
- What site paperwork they can supply
- Their pre-qualification and accreditations
- How joint depth will be controlled
- Whether primer will be used where the manufacturer specifies it
Planned mastic for Botley portfolios
The South East is one of the drier parts of the UK. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first. At about 65 miles from central London, Botley is within reach of the capital. Within reach of London, blocks run by agents and associations are common around stations.
If you own or manage units on a site such as Bottings Industrial Estate, 0.7 miles to the east of Botley, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. Trustees of buildings like Church of All Saints can bring frame and external mastic into a planned maintenance list.
Botley is about 1 mile east of Hedge End, in Hampshire. We cover commercial sites throughout Botley, for single jobs and planned programmes alike. Our Hampshire coverage takes in 723 places, from busy centres to rural villages.

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.
Estate-wide resealing programmes
Using the same products throughout keeps the estate consistent.
Leave it or put it right?
A bead run over old mastic can look like a repair. It won’t grip the old sealant and soon comes away. Full removal and proper preparation is what lasts. In a smaller place such as Botley, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.
A quote for mastic joints depends on how many there are, their condition and the access. Ask us for a fixed quote.
