When it isn’t the sealant
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Damage to finishes by other trades after we’ve sealed
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
If you are not sure, just give us a call on 01277 525 020 or use the quote form and we’ll give you a straight answer before you book.

Construction mastic in Ibworth, done properly
Mastic Doctor has been a subcontractor on construction projects for over 20 years. We price from drawings and the specification, agree the sequence with the site team and seal as areas are released. For construction mastic on a scheme in Ibworth, send drawings through our quote form, or phone or email us to talk it through. We work on sanitary and kitchen joints, window and door perimeters and internal decorators’ caulk, and what we are called in for most is different trades sealing to different standards and snag items on joints that need redoing before handover. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Ibworth is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
For a site near Ibworth, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Send drawings or photographs and the programme and we will quote to suit.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Maintenance after handover
Problems stay small when the joints are checked regularly. In particular:
- Flag uneven or tapered frame gaps early
- Put any product change through the designer first
- Ask cleaners to use soft cloths around fresh sealant
- Don’t schedule sealing before decorators and flooring are done
Once an area is sealed, protect it from following trades. New beads should be left to cure before cleaning or decorating nearby, and that time depends on the product, temperature and joint depth.
Sealing outside when the joint is damp or too cold leads to poor adhesion. Waiting for a dry joint and the right temperature is better than redoing work so external sequencing builds in some flexibility.
Ibworth: questions and answers
Is Ibworth off your patch?
Not at all. Ibworth is within our area. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.
Can you work to our programme on a site in or near Ibworth?
Yes. Send the programme and drawings, and we’ll plan the mastic to suit the stages. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Can you work to our specification?
Specification first, then the maker’s instructions. Preparation, backing and depth follow the product guidance.
What guarantee comes with a mastic package?
It carries a 12-month guarantee on our workmanship. We’re also fully insured for public liability.
How long does a typical visit take?
We plan the time on site around your programme and access. You’ll have an expected duration with the quote.
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Does weather matter for sealant work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Building and refurbishing in Ibworth
Central London is about 50 miles from Ibworth. 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. Ibworth sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager.
Historic houses such as The Vyne (4.8 miles north-east of Ibworth) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. Hospital estates such as Park Prewett Hospital, 3.1 miles to the east of Ibworth, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

How the job changes by surface
Window and door perimeters
Perimeter joints between frames and the structure are the weather line on any new building. They’re sealed with a low-modulus neutral-cure silicone or another product named in the specification and set the depth with backing where needed.
Internal decorators’ caulk
Caulking is often done in a hurry by whoever’s on site. A neat, consistent caulk line makes the decorators’ job quicker.
Site staff or a sealant specialist?
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. For that reason, many FMs and contractors use a sealant specialist from the outset.
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.
For managing agents and facilities managers
Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
