Are there any maintenance tips or recommendations to keep my sash windows in good condition?
Yes, we provide maintenance tips and recommendations to help you keep your sash windows in good condition. As my colleagues would have discussed (if you were present or hopefully by phone or beforehand,) the windows do need full decoration to be completed within 6 weeks (during wet/cold months it may be advisable to only get the inside done initially until it warms/dries up again.) Leaving the windows exposed for too long could leave the windows open to damage. We recommend using lubricant spray yearly along the insides of the frame where the sashes run (or obviously whenever they might get a little tighter when expanding in wetter months. We also recommend you clean the brushes once a year with a warm wet sponge (no products required.) Once a year if you spot any flaking paint externally, just a quick sand and touch up of paint will help to reduce the risk of rot. We always strive to do the best for our customers, just these minor bits of maintenance will ensure that the windows will last for many years to come. If they are not maintained we cannot guarantee we will honour our guarantee as poor maintenance can leave the windows at risk of rot and damage. Any further questions please let us know.
Can you repair or replace damaged or broken glass panes in sash windows?
Yes, we can repair or replace damaged or broken glass panes in sash windows. Our team can assess the extent of the damage and provide appropriate solutions, including reglazing or replacement with matching glass (depending on our supply.) It is important to note for transparency that the replacement of a pane of glass may be more cost effective with a local glazier than the need for a sash window specialist.
Do you offer any financing options or payment plans for window repairs?
As a small family business that is not an avenue we have pursued. We do have a payment structure in place which includes a deposit, middle payment (if double glazing) and final payment on the day of completion. We are able to accept payment by debit or credit card via a secure payment link.
Are your window repair services available in my location?
We provide window repair services across Greater London, Kent, Medway and across the South East of England. Other areas will be considered dependent. Please contact us with your location details, and we will confirm our availability to assist you.
Can you provide references from previous customers who have used your services?
Yes, we can provide references from previous customers upon request. We value our customers’ privacy, but we can share testimonials. If you wish to view similar works, we can supply images and we can try to organise with a previous customer for you to view them in person. This is subject to availability, as we do not wish to pressure any of our customers to invite people they do not know into their homes.
How can I best prepare my windows for the repair process?
To prepare your windows for the repair process, it is helpful to clear any obstacles or furniture near the windows. Additionally, removing any curtains, blinds, or window treatments can make it easier for our team to access and work on the windows. Parking is a vital element to most of our works. Specifically double glazing, we require parking very close to the property for access to power and to avoid our colleagues carrying windows and materials far. With other works we can carry this out with cordless tools, however, parking nearby will still be required to avoid the team carrying heavy machinery far. Please let us know if there are any issues or complications with organising parking nearby so we can assess what is feasible or not.
Double Glazing FAQ
What is double glazing and how does it work for sash windows?
Double glazing involves installing two glass panes with a gap in between to create an insulating layer of air. This layer helps to reduce heat transfer and improve energy efficiency in sash windows by minimising heat loss or gain through the glass.
Can I retrofit double glazing into my existing sash windows?
Yes, it is possible to retrofit double glazing into existing sash windows. Retrofitting involves replacing the single-pane glass with double glazing units while preserving the original sash window frames. Please check out the link to see how the process works Retrofitting – Box Sash Window Repairs Ltd
What are the benefits of retrofitting double glazing in sash windows?
Retrofitting double glazing in sash windows provides several benefits, including improved thermal insulation, reduced energy consumption, enhanced soundproofing, and increased overall comfort in your home. Verses replacements, this is a more environmentally friendly process and the quality of the timber in original sash windows is usually far superior than most of the replacements on offer today.
How does double glazing improve energy efficiency in sash windows?
Double glazing improves energy efficiency in sash windows by reducing heat transfer. The insulating layer of air between the glass panes acts as a barrier, preventing heat from escaping during colder months and entering during hotter months.
Will retrofitting double glazing change the appearance of my sash windows?
Retrofitting double glazing does not necessarily change the appearance of sash windows. There requires a deeper rebate which will reduce the depth of the internal profile. How much so, depends on the thickness of the glazing being installed. With any double glazing, it is quite common that glazing bars will need to be laminated onto a single unit per sash to maintain the appearance of the same thickness of glazing bar. This is purely due to the need to hide the spacer/sightline and doing so means there is not enough space for individual panes. We are able to help supply a clear explanation of this process should it be required for any council applications etc.
What types of glass are used for double glazing in sash windows?
Various types of glass can be used for double glazing in sash windows, including low-emissivity (low-e) glass, laminated glass, or acoustic glass. These options offer different benefits such as improved energy efficiency or enhanced sound insulation. Most commonly we install 4-4-4 and 4-6-4 pilkington toughened low-e argon filled units. The depth of the unit depends on the depth of the sashes themselves.
Can I choose different glass options for my double-glazed sash windows?
Yes, you can choose different glass options for your double-glazed sash windows based on your specific requirements. The selection may include options for thermal performance, noise reduction, safety, or privacy. We are able to supply a link to what options are available upon request.
Is it possible to retrofit double glazing in historic or listed sash windows?
Retrofitting double glazing in historic or listed sash windows can be more challenging due to preservation and regulatory considerations. It is advisable to consult with local authorities or preservation specialists to ensure compliance with relevant guidelines. We are always more than happy to assist as best we can.
How much noise reduction can I expect from double-glazed sash windows?
Double-glazed sash windows can significantly reduce external noise transmission compared to single-glazed windows. The level of noise reduction depends on factors such as glass thickness, air gap width, and additional soundproofing measures in the property.
Does retrofitting double glazing require any alterations to the sash window frame?
Retrofitting double glazing typically does not require major alterations to the sash window frame. The new double glazing units are designed to fit within the existing sash frames, minimising the need for structural modifications.
What is the process for retrofitting double glazing in sash windows?
The process for retrofitting double glazing in sash windows typically involves removing the existing single-pane glass, rebating, installing the double glazing units, ensuring proper sealing and insulation, and making any necessary adjustments for smooth operation. Please see more detail at Retrofitting – Box Sash Window Repairs Ltd
How long does it take to retrofit double glazing in sash windows?
The duration of retrofitting double glazing in sash windows depends on various factors such as the number of windows, their size, and the specific requirements. It can range from a few hours to a few days for a complete installation. Generally speaking a full team will be set up for 3 windows a day, however, if possible then more will be achieved. Smaller jobs will be taken on with a smaller team or booked in alongside other works.
Are there any maintenance requirements for double-glazed sash windows?
Double-glazed sash windows generally require minimal maintenance. Regular cleaning of the glass, lubrication of moving parts, and inspection of seals and weatherstripping are recommended to ensure their longevity and performance.
Will retrofitting double glazing in sash windows affect the operation of the windows?
When done correctly, retrofitting double glazing should not significantly affect the operation of sash windows. Proper installation and adjustments ensure that the windows can still be opened, closed, and operated smoothly. The only difference can be the ‘travel’ (how far they open and close.) This is due to the significant amount of additional weight required for operation, which will make the length of the weight longer. As such the weighting will hit the top/bottom of the box sooner than single glazed. Discounts are on offer to fix the top sashes in place to allow for the depth of the box to be used for weighting, but please ask any questions for further assistance on this.
Can I still open and close the sash windows after retrofitting double glazing?
Yes, you can still open and close the sash windows after retrofitting double glazing. The added weight of the double glazing units may require minor adjustments to the counterbalance mechanism to maintain proper balance.
Are there any additional security benefits to retrofitting double glazing in sash windows?
Yes, for 2 reasons, first is that retrofitting double glazing can provide additional security benefits by offering an extra layer of protection against forced entry. Double glazing is tougher to break than single-pane glass, enhancing the overall security of your sash windows. Secondly, the glazing we install is toughened in both panes.
Will retrofitting double glazing in sash windows eliminate condensation issues?
Retrofitting double glazing can help reduce condensation on the interior surface of the windows. The insulating layer of air minimises temperature differences between the inside and outside of the glass, reducing the likelihood of condensation forming. Ventilation however is the best form of condensation prevention.
What is the cost of retrofitting double glazing in sash windows?
The cost of retrofitting double glazing in sash windows can vary depending on factors such as the number of windows, their size, the chosen glass type, and additional customization options. It is best to request a personalised quote from a reputable window specialist.
Are there any grants or financial incentives available for retrofitting double glazing?
There might be grants or financial incentives available for retrofitting double glazing in sash windows, depending on your location and specific circumstances. It is advisable to research local government programs or energy-efficiency initiatives for potential assistance.
Can I get a warranty for the retrofitting of double glazing in my sash windows?
Yes we offer a 5 year guarantee for all our works carried out including double glazing. Realistically we would expect the glazing part itself to last far longer than 5 years though.
Draught Proofing FAQ
What is draught proofing for traditional timber sash windows?
Draught proofing for traditional timber sash windows involves sealing gaps and cracks around the window frames and moving parts to prevent the infiltration of cold air and the escape of warm air, thus improving energy efficiency and comfort.
Why is draught proofing important for timber sash windows?
Draught proofing is important for timber sash windows as it helps to eliminate drafts, reduce heat loss, improve energy efficiency, enhance indoor comfort, and potentially lower energy bills.
How does draught proofing improve energy efficiency in sash windows?
Draught proofing improves energy efficiency in sash windows by sealing gaps and cracks that allow air leakage. This helps to prevent the exchange of air between the interior and exterior, reducing heat loss during winter and heat gain during summer.
Can draught proofing reduce noise transmission through sash windows?
Draught proofing can help to reduce noise transmission through sash windows to some extent. While it primarily focuses on sealing gaps for energy efficiency purposes, it can also contribute to a certain level of sound insulation by minimising air leakage.
What are the benefits of draught proofing traditional timber sash windows?

Can draught proofing help prevent rattling or movement of sash windows?
Yes, draught proofing can help prevent rattling or excessive movement of sash windows. By sealing gaps and improving the overall tightness of the window, it can stabilise the window’s position and reduce unwanted movement.
Will draught proofing affect the appearance of my traditional timber sash windows?
Draught proofing, when done professionally, should not significantly affect the appearance of traditional timber sash windows. The sealing materials are discreetly installed to minimise any visual impact on the window’s aesthetics.
What materials are used for draught proofing timber sash windows?
Various materials can be used for draught proofing timber sash windows, including specialised brushes, seals, gaskets, and weatherstripping. These materials are designed to be durable, flexible, and compatible with timber frames.
How long does the draught proofing installation process take?
The duration of the draught proofing installation process depends on the number and size of the windows being treated, as well as the specific requirements of the project. Generally, it can range from a few hours to a full day for a complete installation. Multiple windows worth of work may require several days to complete.
Can I draught proof my sash windows myself, or should I hire professionals?
While it is possible to attempt draught proofing sash windows as a DIY project, it is generally recommended to hire professionals. They have the expertise, experience, and specialised tools to ensure proper installation and effective draught sealing.
Does draught proofing require any modifications to the sash window frames?
Draught proofing typically does not require any major modifications to the sash window frames. The sealing materials are carefully installed within the existing structure and moving parts of the window to create an effective barrier against draughts.
Can draught proofing help reduce condensation issues in sash windows?
Draught proofing can help reduce condensation issues, but can also exaggerate them also. By minimising air leakage, it helps maintain more stable indoor humidity levels, reducing the likelihood of condensation forming on the window surfaces. However, in rooms with high humidity the draught proofing removes natural ventilation as a result means that the windows can be more likely to have condensation issues. There are several remedies including small disposable dehumidifiers and ventilating by opening your top sash.
Will draught proofing interfere with the operation of my sash windows?
Properly installed draught proofing should not interfere with the operation of sash windows. The materials used are designed to allow smooth movement of the window sashes while effectively sealing gaps when the windows are closed.
How long does draught proofing typically last before it needs replacement?
The durability of draught proofing materials can vary depending on factors such as the quality of the materials used, exposure to weather conditions, and regular maintenance. On average, draught proofing can last for several years before requiring replacement.
Is draught proofing suitable for historic or listed timber sash windows?
