These units have some amazing features, but they can be high maintenance. A unique set of abilities is required for repairing them. Someone having these abilities, or able to acquire them, and having the necessary business aptitude, will have all the skills needed to begin a sash window refurbishment company.
This type of unit is composed of, most often, two panels made up of several glass panes each. The panes are held together and divided from each other by narrow wooden muntins. The bottom panel will slide along a vertical groove at the side jamb to open. Some panels slide horizontally. A hung sash system, that was at one time common in the US, has both panels movable vertically. They can be opened towards the middle. This allows warmer air from the top of the house to escape while cooler air is drawn in at the bottom, from outside.
These panels can be expected to stay in the position they are moved to, without slamming down. Weights hanging from cords inside the frame balance the weight of the panel, making movement effortless. Springs or compressing weather stripping can also be employed to maintain the panels with the desired configuration.
Numerous problems can occur with the system. The wood they are constructed of can swell or warp, this and carelessly applied paint layers can all make the panel stick. The wood can shrink making the panel tend to slam down to the sill, not staying where wanted. The cords or pulleys can become defective, also causing the panel to slam down under it's own weight, or fail to move at all.
To repair these systems demands some carpenter's talents for disassembling the unit, cutting, and fastening replacement parts or broken glass panes. Additionally, mechanical talents will be helpful in disassembling the unit, finding the defective parts, replacing or adjusting them, and making the system functional again. Hardware replacements may be necessary also.
Laying out the project, measuring, cutting, and fastening parts, all in proper order will help to avoid unnecessary disassembling and redoing. Properly fitting panels and weather stripping will prevent drafts and loss of heat or cooling.
The skills needed to begin a sash window refurbishment company are several. Both carpenter and mechanical abilities are necessary for this project. Patience and the ability to handle detail and perform finishing quality work will help ensure success.
