Construction mastic in Trotton
On refurbishments, the mastic package usually includes cutting out old sealant as well as sealing new work. Old beads come out completely, as fresh silicone can’t grip old. After that, the joints are prepared and sealed to the specification. If you are dealing with cracks opening in caulked internal joints and a mastic package split between trades with no clear owner, we can help. Most enquiries from Trotton start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
For a site near Trotton, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Drawings, photographs and the programme let us give a fixed quote.
What our 12-month guarantee covers is the way we did the job: 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.

FAQs: Trotton
Is Trotton too small for you to travel to?
No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Does your area include sites such as Midhurst Business Centre, near Trotton?
Yes. Our area takes in Trotton and its surroundings, with estates and business parks such as Midhurst Business Centre included. Send details of the unit and the work through our quote form for a quick quote.
When can you be on site?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
When is resealing likely to be due?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Can you handle several sites?
Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
Can you send site paperwork?
Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.
Do you guarantee new-build sealant work?
The work is guaranteed for 12 months. Protecting sealed areas from following trades helps avoid damage.
Facades, frames and programmes in Trotton
At about 46 miles from central London, Trotton is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes. Trotton is in the South East, one of the UK’s drier regions. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so the external programme keeps a little slack.
When a school such as Stedham Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. Older buildings in the area around Trotton, such as Cowdray House (3.2 miles east of Trotton), need care when sealed: the product has to suit soft or historic materials.

Leave it or put it right?
A cheaper sealant can look like an easy saving on a large package. The saving is small next to the cost of callbacks and defects, especially externally. We price the specified product and will tell you plainly where an alternative would or wouldn’t work. Halls, stores and units around places like Trotton may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Should maintenance staff do it?
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
After the work
Cleaning and maintenance staff play a part too. Share these points with them:
- Get the mastic subcontractor involved early in the programme
- Don’t schedule sealing before decorators and flooring are done
- Stick to the specified sealant rather than a generic substitute
- Ask installers to correct oversized gaps first
A new structure shifts as it loses construction moisture. Flexible sealants in the right joints handle normal movement. If that happens, let us know.
In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Water gets behind trays, vanity tops and panels. Getting the product and preparation right first time avoids that.
What we can’t put right
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Oversized gaps that need packing or adjustment by others
- Specifying the product where the designer hasn’t
- Deciding which fire-stopping product a penetration needs
If in doubt, call 01277 525 020 or send photos by email and we’ll say what we think before you book.
Joints and surfaces we work on
- Brick and block movement joints
- Internal decorators’ caulk
- Sanitary and kitchen joints
- Cladding and panel joints
- Floor and skirting junctions
- Window and door perimeters
What we are called out for in Trotton
A new building moves while it dries and settles. Materials lose construction moisture and shrink. Choosing the right product for each joint reduces that.
If one of these sounds familiar, it’s time for a closer look:
- Frame perimeters left unsealed or poorly sealed
- New external sealant already peeling away
- Existing joints on a refurb that need cutting out and resealing
- A mastic package split between trades with no clear owner
New units and refits on sites such as Midhurst Business Centre, 2.5 miles east of Trotton, need their panel and perimeter joints sealed to the specification.

- Their public liability cover
- How the existing material will be dealt with
- How long is the guarantee, and what does it include?
