Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Should maintenance staff do it?
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Construction mastic in Stotfold
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 Stotfold, send drawings through our quote form, or phone or email us to talk it through. If you’re dealing with cracks opening in caulked internal joints and snag items on joints that need redoing before handover, we can put it right, on window and door perimeters, cladding and panel joints and sanitary and kitchen joints alike. For commercial sealant work in Stotfold, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
In a smaller place such as Stotfold, construction tends to mean small housing schemes, conversions and extensions to community buildings. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Facades, frames and programmes in Stotfold
The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so external mastic is timed for workable conditions and agreed with the site manager. Stotfold is about 36 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme.
Extensions at sites like Fairfield Hospital (to the south-west of Stotfold) usually sit beside working departments, and the mastic follows strict access rules. Older buildings in the area around Stotfold, such as Hinxworth Place (2.4 miles north-east of Stotfold), need care when sealed: the product has to suit soft or historic materials. When units on a site such as Letchworth Gateway Retail Park (2.6 miles south of Stotfold) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Surface by surface
Window and door perimeters
Internal perimeters are usually sealed with a paintable product where decorating follows. The specification decides which with colours matched to the frame where needed.
Fire-rated sealant where specified
Fire-rated sealant forms part of some packages, installed to the product’s tested detail where it is specified. Fire stopping design belongs to the designer and building control and we install what’s specified.
How a job runs
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then handed back before the next one starts.

What sealant work can’t fix
Before quoting, we check that sealant is the right answer. It won’t put right:
- Specifying the product where the designer hasn’t
- Frame gaps too wide for sealant, which the installer needs to correct
- Approving fire stopping as compliant
If you are not sure, just call the office on 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.
Where we work in Stotfold
- Floor and skirting junctions
- Internal decorators’ caulk
- Window and door perimeters
- Brick and block movement joints
- Sanitary and kitchen joints
- Cladding and panel joints
Keeping the joints sound
To get the most from the new sealant:
- Record the products used in the O&M file
- Brief following trades on areas that have been sealed
- Plan external elevations with the weather in mind
- Share drawings and the specification as soon as possible
A new structure shifts as it loses construction moisture. The right product in each joint copes with that. If that happens, let us know.
Oversized gaps are a problem better caught early. Sealant stretched over an oversized gap won’t last so packing or adjustment by the installer comes first. We raise them during our first walk of the area.
