What we’re called out for in Hythe End
On construction sites, joints usually fail early because of when they were sealed, not what was used. If sealant goes in before the last trades are through, it gets knocked, painted over or contaminated, and the joint has to be redone.
If one of these sounds familiar, it’s time for a closer look:
- Perimeter gaps outside the sealant’s range
- Old sealant on a refurbishment that needs stripping before new work
- Sanitary sealant damaged by following trades
- Early adhesion failures on new external joints
University estates such as Royal Holloway University, 1.6 miles south-west of Hythe End, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.

About our construction mastic in Hythe End
Mastic Doctor has been a subcontractor on construction projects for over 20 years. Quantities come off the drawings, the sequence is agreed with the site manager and the work follows the trades. To price a package in Hythe End, send drawings and the specification through our quote form. If you have a long mastic snag list close to completion and external joints sealed in damp or cold conditions that are now failing, we can put it right. Whoever orders the work in Hythe End, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Around smaller places like Hythe End, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Site staff or a sealant specialist?
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
What sealant work can’t fix
A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
- Designing joint widths or choosing the specification (that sits with the designer)
- Frame gaps too wide for sealant, which the installer needs to correct
If in doubt, ring 01277 525 020 or use the quote form and we will say what we think.

Your questions answered
Do you take on work at healthcare sites like Ashford Hospital?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Will you take on work at estates like The Green Business Centre, close to Hythe End?
Yes, sites like The Green Business Centre are within our area, along with the rest of Hythe End. Photos and a short description are enough for a first look.
Who decides which product is used?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

How the job changes by surface
Kitchens and utility areas
Commercial kitchens often need hygienic or food-safe sealants. We follow the specification and seal to a smooth, cleanable finish.
Snagging before handover
The last pass before handover is where mastic snags are cleared. Snags are cleared room by room and damaged joints are redone rather than patched.
Commercial clients in Hythe End
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.
We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.
