HOW TO INSTALL SASHCORDS

We do both sash cords and spiral balances in double hung windows

In this page we have included information for the DIY home handyman.

 

Sash cords take on average 11 minutes per cord, i.e. 45 minutes per window, costing $180, less discount for volume.

 

Below are some steps helpful to change the cords yourself.

To determine the difference between sash cords and spiral balances, see here.

 

See Six Steps to change chords below.

SASHCORDS VS SPIRAL BALANCES

Sashcords are the ropes in timber sash windows.

If it’s a black plastic pipe instead of ropes, see “Spiral Balances Install”

 

See PRICE GUIDE link if you are getting someone to do them.

FEED THE NEW ROPE

Use the  “mouse” to FEED the new cord through, via the “box cover”. The entire job revolves around opening the box cover (video) and requires some confidence and strong manipulation to release.

TIPS

It can help to cut the end of the new rope so it is not “fluffy”.

Having the string ON TOP of the cord when feeding in helps the rope pull into the pulley

Video “How-To-Change- sashcords”.

A standard scraper is too flexible to open the stop and parting beads.

 

CUT LINE DOWN THE STOP BEAD WITH A BLADE

This may help the stop bead come away in a smooth line sometimes.

PARTING BEAD

TO SAVE PAINTING

Lay off the stop bead and parting beads with “No More Gaps” using a saturated wet rag.

ISSUES AND 5 STEPS TO CHANGE SASHCORDS

An experienced tradesman will probably take on average about 11 minutes a cord to change over sashcords.

AVOID THIN REPLACEMENT SASHCORD

Thin (6mm or 7mm) cord has a tendency to jump off the pulley.

CHANGING CORDS ISN’T RESTORING FUNCTION

If you are painting soon, ask someone to ‘do what is needed’ rather than just saying ‘sashcords’. For example, you may want the top sash to work again.

Weights may be wrong; seven layers of paint in the track may inhibit movement; beadings may need a change.

WINDOW REPAIRS AREAS COVERED

Randwick, Coogee, Maroubra, Malabar, Rose Bay, Watsons Bay, Bondi, Bondi Junction, Edgecliff, Double Bay, Rushcutters Bay, Paddingon, Centennial Park, La Perouse, Dover Heights, Elisabeth Bay, Potts Point, Eastlakes, Botany, Mascot, Newtown, St. Peters, Enmore, Five Dock, Ultimo, Marrickville, Drummoyne, Annandale, Leichhardt, Erskinville, Stanmore, Petersham, Camperdown, Haberfield, Ashfield, Croydon, Croydon Park, Burwood, Summer Hill, Auburn, Kingford, Pagewood, Summer Hill,

HERE ARE THE STEPS

STEP 1

8mm sash cord rope is optimum rather that 6 or 7mm.

French windows (heavy) which go down to the floor, use 10mm.

STEP 2

Using a box cutter, cut a line in the paint down the stop bead and remove the first stop bead, cutting the other cord if only one was broken.

STEP 3

Lift the entire sash out, then dislodge the second beading, the parting bead, and you will discover the “box cover” which you gently prise out at its bottom.

STEP 4

A thin string with a small weight is fed down from the pulley which is attached to your new cord. Lead or lead fishing balls are best.

image

Run the string across to the other side of the window, preferably after you have taken the weights out on both sides. Knot the rope into each weight with a double knot, cutting the first rope a foot down from the pulley.

STEP 5

It’s sometimes worth checking the comparative weight of the removed sash, and the weight of the combined weights of the window. Add lead to balance. This occurs sometimes with someone putting heavier glass in once before, which is common.

Old homes had 2mm glass, and if changed subsequently, became 3mm glass. It could be a lot if  sound reduction glass has been installed.

STEP 6

Squirt into the pulleys with WD40 for the squeaking noise.

 

MOST FREQUENT PROBLEM – WRONG WEIGHT

Cords are fine but the window won’t stay up. The proverbial stick holding the window.

HOW TO FIX

A lot of people don’t realise that the reason a window won’t stay up is due to incorrect weights, even though both sashcords are still intact.

ADDING WEIGHT

To add weight, one or both cords have to be cut.

ONE CORD

If it is only a small disparity, just one cord will do;  the side that seemed to drop more than the other. Try for 2 kgs of lead.

Insert additional weight onto the NEW rope before tying in the pre-existing cast iron weight.

BOTH CORDS

If the weight was radically wrong, both cords.

 

UNUSUAL SASHCORD SYSTEMS

See blog for more videos.

Weights only on one side

Guillotine timber sashcord windows

Windows where no box cover was present to access the weights. Guillotine windows are windows which completely recess down into the wall cavity.

 

NEW WEIGHT

A roll of lead flashing, minimum $45 for 10 kgs at the hardware. No other solution, except to drive to Rockdale after  weighing your sash on bathroom scales, and buying equivalent weights as I just had to do for a job in Darling Point that required 10 kgs for a single sash.

The best time to repair windows is before the painters and bathroom/ kitchen installations, seen here in Darling Point.

MAKING ADDITIONAL WEIGHT FROM LEAD FLASHING

Extend the flashing and roll lead around TWO pieces of sashcord, tapping with a rubber mallet until the thickness ends up the same as the sash weight that came out and roll the result in Duct tape.

Saw to weight, giving yourself an assorted selection.

Balance sides on the scales and fit.

BALANCING THE SASH WEIGHTS

Half each side.

LAYING OFF STOP BEADS

Use “No More Gaps” down the replaced stop beadings with a wet rag to save any painting.

SETTING THE NAIL POSITIONS

See How-To-Videos on setting the rope lengths for the nails in for both the lower and upper sashes.

Function to the top sash  will allow hot air in the room to escape, vital for shower areas to help prevent mould.

FRICTION STAYS

Friction stays relate to timber windows that hinge from the top

ROT REPAIR

Unexpected discoveries often arise when addressing double hung windows; particularly rot damage.
