How we handle facade sealing in Gerrards Cross
Water ingress at window frames is a frequent reason facilities managers contact us. Failed perimeter sealant is a frequent cause, though that isn’t the only cause. We will tell you if we think the leak is coming from somewhere sealant won’t fix. The enquiries we see most involve failed seals around shopfront and entrance frames and water coming in around window frames, across stone and brick facade joints, coping and flashing joints and cladding panel joints. Looking for mastic applicators who cover Gerrards Cross? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Building work in places the size of Gerrards Cross is normally small-scale: a handful of new houses, barn conversions, a school or hall extension. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

General trades versus a specialist
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.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Gerrards Cross: questions and answers
Can you work on a hospital site such as Spire Thames Valley Hospital?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Is Gerrards Cross too far out for you?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Do your applicators hold CSCS cards?
Yes. Our applicators hold CSCS cards, which many sites require.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Is any job too small?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
Do you provide access for facade work?
We agree access with the client at the start. Let us know what access is in place or planned.
Can you work in cold or wet weather?
Rain and frost can pause external sealing. We plan for weather and keep you updated throughout the job.

When to call us in Gerrards Cross
New sealant run over old sealant rarely holds. Fresh silicone won’t stick to cured silicone, and the patch soon lifts.
Any of the following is a good reason to get the joints checked over:
- Sealant pulling away from frames or panels
- Leaks at window and door perimeters
- Cladding panel joints that have opened up
- Cold air coming in at window perimeters

Cost factors for facade joints
We price every job individually. The main factors are:
- Removal of failed or old sealant
- Access and working height
- Induction, permit and paperwork requirements
- Which sealant the job calls for
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
Details that help us quote
However big the job, these details speed things up:
- The asbestos register, for older buildings
- Your programme or deadline
- The site address and postcode
- A wide shot and a close-up of the area
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.
From enquiry to sign-off
At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. Work in places the size of Gerrards Cross is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- We look at the joints, the drawings and the access before pricing.
- Failed sealant is cut out along its full length.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- The new sealant goes in and is tooled firmly onto both faces.
- The completed runs are checked with you, then the 12-month guarantee applies.
Preparing the site
- Share your working hours and any access restrictions
- Let building users know which areas are affected
- Tell us what induction or permit system the site runs

Advice
When it isn’t the sealant
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Providing access systems for the work
- Joints too narrow for the movement they take, which need redesign
- Render or concrete edges that have broken away
If in doubt, phone 01277 525 020 or email us and we’ll say what we think before you book.
Where we work in Gerrards Cross
- Perimeter joints where frames meet the structure
- Coping and flashing joints
- Shopfront frames
- Window and door perimeters
- Stone and brick facade joints
- Cladding panel joints
After the work
To get the most from the new sealant:
- Add perimeter sealant to planned maintenance checks
- Investigate damp beside windows promptly
- Share access with other external trades
- Ask about asbestos in pre-2000 mastic
Let the new sealant cure before washing the facade or windows near it. Pressure washers and harsh cleaners can damage a fresh bead, so brief your window cleaners.
Tie resealing in with redecoration, cladding repairs or other access. Sharing the access keeps the cost down.
