About our mastic sealing in Gubblecote
Treatment starts with a proper look: what has failed, what caused it and whether new sealant will actually solve it. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in and backing rod used wherever a joint is deep. Most enquiries involve brittle perimeter mastic across a building and complaints coming in block by block, across external wall and movement joints, shopfronts below residential blocks and window and door perimeters on blocks. Looking for mastic applicators who cover Gubblecote? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
For owners with a single building near Gubblecote, we plan to finish in one visit where possible. Send photos of the frames and joints and we will give a fixed quote.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

When something else is needed
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:
- Masonry that has broken away beside the joint
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Leaks through the frame itself rather than the perimeter
If in doubt, speak to us on 01277 525 020 or send details through our quote form and we will say what we think before you book.

What else we do in Gubblecote
Looking after the joints
Once the work is signed off, these steps help:
- Share your contractor requirements early
- Ask residents or tenants to report leaks and draughts early
- Protect low-level joints in entrances
- Track which buildings were done and when
Keep bins, bikes and deliveries away from low-level joints where you can. Damage at low level is the most common reason communal joints fail early.
The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing and the job grows.
Planned mastic for Gubblecote portfolios
Rainfall across the South East, Gubblecote included, is lower than in many parts of the UK. Outside work still depends on dry joints, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first. Gubblecote is about 34 miles from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres; their frame mastic often ages block-wide.
For owners of several units at places like Old Airfield Industrial Estate, 0.9 miles north-east of Gubblecote, one programme can deal with frame and external mastic across the lot. Older community buildings, St Cross among them, often have frames of mixed ages whose mastic varies.
Gubblecote is about 6 miles east of Aylesbury, in Hertfordshire. We cover commercial sites throughout Gubblecote, for single jobs and planned programmes alike. Gubblecote is one of 371 places in Hertfordshire on our list. Oxford is covered too, around 24 miles from Gubblecote.

For managing agents and facilities managers
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
We work for building owners and managing agents on everything from one building to a spread of sites. Several sites can go on one quote, which keeps the paperwork simple.
When to call us in Gubblecote
Frames, panels and masonry expand and contract through the year, and every joint has to stretch and squeeze with them. A joint that was too narrow, too thin or the wrong product can’t cope long before it should.
Most enquiries start with one or more of the following:
- The same joint failures repeated across a portfolio
- Open joints in brickwork or panels
- Worn sealant at communal door frames
- Complaints coming in block by block
Site managers at schools like Long Marston VA Church of England Primary School can fit frame mastic into the summer works.
Before you book anyone
- Will failed sealant be removed rather than covered?
- What site paperwork they can supply
- Health and safety accreditation such as CHAS
- What level of public liability insurance do they hold?
From enquiry to sign-off
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. If others near Gubblecote need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- A building-by-building inspection lists the failed joints.
- The quote is fixed and split as suits you.
- Dates and areas are agreed so occupiers can be told.

Advice
Common questions from Gubblecote clients
Do you work for managing agents with blocks near Cheddington station?
Yes, and several blocks can go on one quote. Send the address, photos of the elevations and your access arrangements, and we’ll give a fixed quote.
Is Old Airfield Industrial Estate, near Gubblecote, within your area?
Yes. Our area takes in Gubblecote and its surroundings, with estates and business parks such as Old Airfield Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
How many days will you need on site?
That varies with the scale of the job, but the work typically takes a few days for most blocks, with larger programmes scheduled building by building. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Can people stay in the building while you reseal?
Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so you can arrange it with occupiers.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
