What sealant work can’t fix
Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:
- Joints damaged after sign-off by following trades
- Frame gaps too wide for sealant, which the installer needs to correct
- Designing joint widths or choosing the specification (that sits with the designer)
Not sure which it is? You can speak to us on 01277 525 020 or send photos by email and we will tell you honestly before you book.

Construction mastic for commercial buildings in Compton
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 Compton, send drawings and the specification through our quote form. Site teams most often ask us about inconsistent sealant finishes from plot to plot and missed perimeter joints on a new elevation, on internal decorators’ caulk, cladding and panel joints and sanitary and kitchen joints. A specialist sealant contractor works differently from a general builder: on jobs in Compton, preparation and product choice get the time they need.
For a site near Compton, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Drawings, photos and the programme let us give a fixed quote.
Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

General trades versus a specialist
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
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 typically costs more in the end than doing them right.
Diagnose, treat, sign off
On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work usually takes anything from a day of snagging to several weeks of plot-by-plot sealing on a phased scheme. Rural sites near Compton may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- We start with the drawings, specification and programme.
- We take off quantities and return a fixed quote.
- We agree with the site team which areas come first.
- Each area is sealed when it’s released.
- Joints are prepared, backed and sealed to the specification.
- Snags are cleared and the package signed off with our 12-month guarantee.
Getting the site ready
- Flag any permit to work we will need
- Let building users know which areas are affected
- Point out parking and an unloading spot
Quotes
Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.
Advice
Why deal with it now?
Refurbishments sometimes budget for new windows when the frames are sound and only the seal has failed. If the frame is in good order, cutting out and resealing the perimeter can be all it needs and that’s a far smaller job. If the frame is life-expired, we will tell you. Older rural buildings around Compton move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Looking after the joints
After handover, these steps help:
- Ask cleaners to use soft cloths around fresh sealant
- Bring the mastic contractor in after the last trades are through
- Record the products used in the O&M file
- Ask installers to correct oversized gaps first
Once an area is sealed, protect it from following trades. New beads should be left to cure before cleaning or decorating nearby.
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 so packing or adjustment by the installer comes first. We raise them during our first walk of the area.
Construction mastic around Compton: points for this area
At about 50 miles from central London, Compton is within reach of the capital. 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. Compton 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.
For contractors building in or near Compton, we seal to the drawings, the specification and the programme. Projects at schools like Compton C.E. Primary School work to term dates, so mastic is programmed tightly.

FAQs: Compton
Is Compton off your patch?
No. Places such as Compton are covered as much as the big towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
What site paperwork comes with a job in Compton?
We will confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We are CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.
Are you CHAS accredited?
We’re CHAS accredited and a Constructionline member, with CSCS-carded applicators. We are also fully insured, with five million pounds of public liability cover.
Do you guarantee new-build sealant work?
It’s backed by our 12-month guarantee, covering how we sealed. Keeping other trades off finished joints prevents most problems.
Will you just go over the old sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Do you do fire-rated sealing on new builds?
It can be part of the package where specified. Record requirements are confirmed at quote stage.
Do you take on small jobs?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
