Mastic sealing for Catherington sites
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Aftercare for building managers
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Include mastic in your cyclical inspections
- Track which buildings were done and when
- Plan resealing building by building rather than complaint by complaint
- Make it easy for occupiers to report draughts
Log the date and extent of the resealing for each block. It helps plan the next round and shows what was done.
Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings so spending is spread.
How we handle mastic sealing in Catherington
Older blocks and commercial buildings can have mastic that contains asbestos. We check the asbestos register or survey before any old sealant is cut out, and work stops for testing if there’s any doubt. We don’t remove asbestos-containing materials. Most enquiries involve old repairs sealed over failed mastic and worn sealant at communal door frames, across balcony and threshold joints, communal kitchens and washrooms and shopfronts below residential blocks. One point of contact handles commercial sealant work in Catherington from the first photos to the final walk-round, whether it’s one building or several.
Owners and agents with buildings around smaller places such as Catherington tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Commercial clients in Catherington
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
How the quote is worked out
The price varies from site to site. It mainly depends on:
- Joint width, depth and condition
- Any access equipment needed
- How much there is to seal
- The product specified
The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.
What to include in your enquiry
A good diagnosis starts with the right details. Let us know:
- Drawings or a marked-up plan, if available
- Whether the building will be occupied during the work
- Where the site is, with the postcode
- When you need the work done

Related advice
Should maintenance staff do it?
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
What we can’t put right
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Misted or failed double-glazed units
- Substrate edges that need repairing first
Not sure which it is? You can call the office on 01277 525 020 or send photos by email and we will tell you honestly.
What we seal
- Balcony and threshold joints
- Shopfronts below residential blocks
- Communal kitchens and washrooms
- Window and door perimeters on blocks
- Communal entrances and stairwells
- External wall and movement joints

Common questions from Catherington clients
Will you work in a care home in Catherington without moving residents out?
Yes. Care settings are planned area by area, at times agreed with the home. Noise and disruption are kept to a minimum.
Do you work for managing agents with blocks near Rowlands Castle station?
Yes, we work for agents, landlords and housing associations with blocks of every size. We work to your notice and access arrangements.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
Do you supply RAMS and insurance details?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.
How long does a typical visit take?
It depends on the scope, but the work typically takes one or more days per building, depending on the joint lengths and the access. For bigger or phased jobs, we will set out a timescale with the quote.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
