How we handle construction mastic in South Stoke
Mastic tends to be one of the final packages before handover, so it lands at exactly the point the programme is tightest. Mastic Doctor takes on mastic packages for main contractors and developers on schemes in South Stoke, sealing plot by plot or floor by floor as areas are released. We work on sanitary and kitchen joints, cladding and panel joints and internal decorators’ caulk, and what we are called in for most is bath and shower joints scraped during the final clean and internal caulk splitting as the building dries out. Facilities teams, main contractors and managing agents in South Stoke tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Construction in and around smaller places such as South Stoke is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Advice
Common questions from South Stoke clients
Is South Stoke too small for you to travel to?
No. Places such as South Stoke are covered as much as the big towns. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Will you fit the mastic around our build programme in South Stoke?
Yes. The mastic is planned around your key stages. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
How long does a job like this take?
The duration is planned around your programme and the access we’re given. You will have an expected duration with the quote.
Is colour matching possible?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.
How do you work with the site programme?
We work to your programme. Share the release dates and we will match our work to them so sealing follows the trades.
Can you work while the building is occupied?
In the majority of cases, yes. Phased work can be planned so areas stay in use.
What joints do you seal on a new build?
It depends on the specification, but most packages include frame perimeters, sanitary and kitchen joints, caulking where specified and a snagging pass.
Why act early in South Stoke
On a refurbishment, there’s a choice between resealing existing frames and replacing them. Sound frames often need only a new perimeter seal and that’s a far smaller job. If the frame is life-expired, we will tell you. One visit to deal with every failing joint makes more sense than several trips to a place like South Stoke, rather than one at a time. Send photos of each area and we’ll quote for the lot.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Common problems we fix in South Stoke
Shrinkage and settlement in the first months put new joints under strain. Materials lose construction moisture and shrink and internal caulk in a moving joint is typically the first to crack. Picking a flexible sealant where there’s movement keeps snags down.
Any of the following is a good reason to get the joints checked over:
- A long mastic snag list close to completion
- Frame perimeters left unsealed or poorly sealed
- Different trades sealing to different standards
- Existing joints on a refurb that need cutting out and resealing
Historic houses such as Basildon Park, 3.5 miles to the south of South Stoke, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.
Comparing quotes
- Health and safety accreditation such as CHAS
- Whether their applicators hold CSCS cards
- Which product they’ll use, and why it suits the joint
- What site paperwork they can supply
Doing it in-house
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
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. That’s why many clients bring in a specialist from the beginning.
Owners, agents and contractors
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.

Looking after the joints
After handover, these steps help:
- Don’t schedule sealing before decorators and flooring are done
- Get the mastic subcontractor involved early in the programme
- Don’t force external sealing on a damp or frosty day
- Brief the final clean team to avoid blades near sealant
Record which products went where in the handover file. Future maintenance is easier when the products are known, and tells you what to reseal with. Tell us what records you need and we will confirm with the quote.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Filling a wide gap with sealant alone sets up a failure. We raise them during our first walk of the area.
