Commissions Procedure – T&Cs

Commissioning work from us is a fairly simple process. We’ve put together this guide to help make things clear from the start.

1. Confirmation

Once you’ve chosen your design and are certain that you’d like to have something made, please write, telephone, or email us to confirm that you wish to proceed. We will agree an approximate timescale.

2. Deposit

We ask for a deposit of a third of the total amount of the order before we produce drawings of your panels. If we are renovating old panels the above applies before removing or starting work on them

3.Drawings/Design/Glass choice

Once we receive your deposit, we produce actual sized drawings for your approval. If after drawing you would like to alter the design or start again with a different design, the cost may increase, or decrease according to its comparative complexity.In conjunction with your drawings and instructions, we will choose glass colours and textures from our samples for the various parts of the design. Glass samples can only be treated as a guide as, due to the nature of manufacture, we are unable to guarantee the glass colours and textures used will exactly match the samples. Much of our glass has within, or on it’s surface, air bubbles, bumps, lines, swirls and faults, if you choose imperfect/antique style glass we will include these within your order. Once your order has been made, we are unable to remove individual pieces of glass to change them, we can make another panel using different glass but would need to make an additional charge to do so.


At a time convenient to you, we will visit the site and fit your panels. When fitting a lead light or stained glass lead light to an existing window or door that has a putty angle, we will “hack” this off, if beaded we will remove the existing beading as carefully as we can.

We do not get involved in woodwork and will not be responsible for replacing beading should it break. We will then remove the existing glass as carefully as we can. If the glass is set in putty or sealant, the old glass generally gets broken into many pieces. We will then “hack” off the putty on the up-stand and glazing rebate and/or remove other sealants (often putty and other glazing materials are harder than the wood they are attached to and removing them can sometimes result in some damage to the wood, we will look to minimise this but will not be responsible for this damage). Once the glass has been removed, the glazing rebate and up-stand cleared, if suitable, we will apply a “bedding” in putty, however we must point out that traditionally lead lights are often glazed dry. We will then fix the lead light in position using tacks finished with a putty angle, or using the beading we removed after having given it a, “light” sand.

During glazing, existing paintwork and wood surrounding the glazed area on both sides can get damaged, we will do our best to minimise this, but will not be held responsible for any damage caused to the adjacent woodwork. We advise every client that the surrounding area will need decorating afterwards by a third party. Very rarely the structure of a door or window may be weakened resulting in it changing shape, or droping in the glazing process, it is very difficult to predict this and we will not be held responsible if the glazing process causes this to happen.

5. Final payment

The balance payment is due on the day of fitting/delivery, or collection of your lead lights, or stained glass lead lights. Please make cheques payable to Coriander Stained Glass, or bank transfer to The Co-operative Bank Sort code 08-92-99 account no. 69004089. We do not accept payment by credit/debit card. Should final payment not be available on the day of fitting/delivery, we reserve the right to remove our products from your premises should our representative and yourself not be able to agree an alternative payment arrangement. If we have not received full payment within 30 days of fitting/delivery we further reserve the right to charge interest on the outstanding balance at a rate of 5% over the standard borrowing rate issued by Barclays Bank on the 30th day of default.

Interim payments

If your order is complete, and you are not ready for them to be fitted/ delivered or collected, we will ask for full payment less the fitting or delivery cost.
Leaded lights – timeframeFor lead lights and coloured glass lead lights our lead time is generally 4 to 6 weeks, painted glass will depend on what is involved but will generally be longer. Church restoration projects will often take very much longer, but we should be able to give a timescale at the time of quotation. Our lead time may be subject to change according to our workload at any given time.

Supply only

If we are just going to supply your lead lights or stained glass lead lights we will not carry out site visits and ask the client to supply sizes. Sizes provided to us need to be the overall size you wish the lead light or stained glass lead light to be, a guide would be to take the tight wood to wood size (outside any beading or putty angle), and take off 3mm on each dimension. We generally surround our lead lights with a thicker border lead for the glazing rebate, typically 12mm or 15mm, it looks better for the lead to stand a little proud of the rebate up-stand, so that you have a small amount of lead surrounding the panel, if you can also supply us with the sight size ( the visible glass size, so that if the panel was made this size it would fall straight through ), we can then determine the correct size of border lead to use.

Damage to leaded lights and stained glass

The most important thing to remember is that with a big enough impact glass can break, the slamming shut of a door or window can cause this the happen. Slamming, constant rough use of a door or window, or sticking woodwork can also cause the lead structure to deteriorate prematurely, resulting in bowing, or weakness. Broken glass and lead structures can be repaired or rebuilt but at an additional charge, as we cannot be responsible for this damage.
QuotationsQuotations are valid for 3 months from their date.
Postal deliveriesDamage occurring during transit must be reported to us within 24 hours of receipt of your glass.

Glass painting

Glass painting is done by hand in the traditional way, colours are kiln fired so they are permanent, it is normal using this method for paint colour not to be consistent and to change to varying degrees while kilning. Kiln fired can result in devitrification which is a chemical reaction giving a blotchy sheen seen on the outside of the glass with the light reflecting off it, this can be seen on some of the finest painted glass, and if paintings are commissioned from us it is on the basis that if this occurs it will be accepted by the customer.


We endeavour to ensure the highest level of workmanship and service. Should you have a grievance with our company, we would be grateful if you would contact us as soon as you become aware of a problem and we will try and rectify it as best and as quickly as we can.
