Restoring sash windows
Hi,
Does anyone know or can recommend sash window restoration/replacement company that will cover North County Dublin? We have three sash windows on our stone cottage (c. 1905), which need either restoring or replacing.
I am unsure how bad they have to be before they must be replaced?
Windows are 6 over 6, have no weights/pulley visible (must have been ripped out), and we can't open them.. due to years of over painting I should think. One pane is cracked but the rest look ok. There's some small amount of wood rotting at the bottom of one of the windows as far as I can see.. though difficult to tell how bad the windows are underneath all the paint. They still keep out the wind and rain though!.
Appreciate any advice. Thanks

Re: Restoring sash windows
Hi,
Sorry I can't help with company listings for Dublin, I'm sure others can - there's certainly many of them around nowadays.
But do hold onto the glass - so often people go to all the expense and effort to get the sashes restored, or replaced if necessary, all with the best intentions, but then get new glass put into the sashes.
The original glass is half the charm of original windows; they literally lose their soul with flawless mirrors of modern glass inserted in the originals' place.
As for the rotting bottom rail - that's probably the most common feature of deterioration with sash windows, and is usually not indicative of widespread rot. Normally the bottom rail is simply taken out and a new timber spliced into place.
And if the years of paint have caused a problem with causing the windows to stick, they've probably saved you from another by protecting the wood beneath!
Hope it goes well for you

Re: Restoring sash windows
Thanks very much for that information Graham.. I will certainly keep the glass where possible. And I'll cross fingers you're right regarding the rest of the wood

Re: Restoring sash windows
THANKS to everyone!!!! That's a real help. I shall now contact one of them.
I tried last year to get these windows restored - contacted two companies listed in the yellow pages (one in North Central and one in West Dublin) One agreed to come an 'assess' the windows.... one said he'd ring back.... neither turned up, despite the fact I rang them back twice.
Hope I have better luck this time. I will post if I succeed !
Thanks again.

I'm well aware of who Bolgers/Ventrolla are and having seen some of their work I have to say as a seasoned craftsman/ window restorer I'm not impressed.
I even understand they now use plastic parting beads, I would have thought the bigwigs in Bolgers should know that plastic expands at a far greater rate than wood and will cause it to split.
If your quote for getting the windows draught-proofed using wooden parting beads and wooden staff beads (matched to the originals), using the best of fittings, re-balanced, and a totally smooth operation is more than €800 then thanks but no thanks.
I'll just have to keep on doing it for my customers like I always do.

I note you have not compared prices nor have denied that restoration is not what Bolgers do anymore.
I had a good look at the website and note they talk a lot about conservation but isn't conservation is where you keep the old ones in place not throw them out onto a skip or whatever.
Restoration is where you repair the damaged ones and get them back to a sparkling state, this is what I do and very well too:D
I've always thought that grants should be available for restoration not for ripping out perfectly good windows and replacing them with sashes that any joinery could make, Bolgers or otherwise.
I also note that you have not understood what I was talking about when I spoke about using plastic parting beads, What I meant was when it expands it splits the side of the frame.

Remove the sashes from the frame,
Remove old pulleys,
Strip the paint from the frame,
Install new pulleys.
Remove excess paint from the sashes,
make a groove in the top of the bottom sash to allow a pile carrier to be installed for draught proofing.
weight the top sash then install it.
cut and install parting beads with no draught brushes showing.
Weigh the bottom sash then install.
Cut staff beads to length.
Attach ring pulls, lifters and fasteners
Small window €800 on average
Big windows €900 on average
larger orders are less.

I have done several restoration projects over the years and I have never heard of any man doing 4/6 windows in 1 day,
Pot Noodle, you still haven't compared prices nor have answered to whether or not Bolgers/Ventrolla do restoration and repair of old sash windows or not.
Since Pot Noodle isn't keen to answer my question maybe I should make a new thread entitled
Do Bolgers/Ventrolla restore sashes anymore? If so, what does it cost?

You may drag it out to justifie €800 a window we just get stuck in the days of ripping people off is long gone value for money now

I'm in the middle of having all the windows at the front of my Victorian house done, including a large bay window.
I shopped around quite a bit and was very unimpressed with W J Bolder aka Ventrolla. The reason my windows need attention is that Bolger's did them around ten years ago and removed part of the original frames and replaced them with plastic which has caused the wooden surrounds to split and rot. They also infilled part of the windows with silicone which sealed in water and caused further decay of the timber. They removed some of the original wrought iron and solid brass catches and replaced them with brassed catches and fittings which have since corroded.
Having spoken to Bolders I found them very unhelpful and uninterested in conservation. I explained that I wanted to retain as much of the original materials as possible, and they said they'd f@ck them out and replace them with new ones. They also failed to return calls, failed to turn up at the appointed time and were reluctant to return a sample sash I had given them for assessment.
In the end I settled for someone who is charging me more than twice the €800 per window price quoted, but I am very pleased with the quality of the work, and am satisfied that I won't need to redo it in a few years like I've had to do with Bolger's.
Part of the reason my price is higher than the €800 is that they are fusing cracked glass back together and hand blowing new cylinder glass to replace modern panes.
They may not be the fastest workers, but I really don't see how anyone could claim to restore six sash windows in a day and do anything like a proper job.

The plastic is an isopon based product i would slice with salvaged timber myself 4/6 windows again i say depending on condition some windows have very little wrong with them i.e weights ,sash cords missing beads & over painting i work for myself so there is no incentive to skive off like i said we just get stuck in

I'm talking about proper restoration though, not patching them up with plastic bits.
As a minimum a restored window will need a printer, undercoat and gloss. How do you manage to get all three coats on and dry in one day, and on six windows? Not to mention replacing damaged timber, replacing cords, rehanging weights, removing old puty, waiting a month for the puty to dry before painting, etc?
