Noisier after replacing soffits and fascias

[Jimbo-Winch]

My wife is quite sensitive to noise. We live near an A road so there's a fair bit of road noise, so a couple years back we got the windows replaced with laminated double glazed uPVC windows. This made a big difference. We just got our soffits and fascias done as the original plywood ones were rotting away. The road noise has suddenly increased again.

It's 60s house where the window is high and the soffit basically comes out right above the top of the window.

The installers assured me that since the joint between the window and the sofit had been sealed the noise couldn't be because of their work.

Not sure what to do or how to sort this out!

Any advice appreciated.

What material are the soffits and fascias? UPVC?

I think you would need to remove the bottom couple of roof tiles and fit some insulation.

Yes uPVC

Thank you I had wondered about whether insulation inside the soffits would help, although the sound does seem to be coming from the top of the window rather than through the ceiling.

I had also wondered whether some acoustic sealant at the top of the window frame would help?

Well Jim without seeing what it was like before I
would start by sealing the window.

Yes once the timber soffit and fascia is removed for a plastic one it will be louder I’m afraid. You’ll need to pull a few tiles off and sort the sealing out from inside the eaves and as catlad said shove some insulation in there (but not loads so it causes a ventilation issue)

Hi jimbo, bit late to the party!

Hope your still active on this forum

Had exactly the same done new windows and upvc soffits and fascias with a new roof. Noise started last october shortly after works completed

I now have a constant 24/7 low hum/drone through the window. Did you ever find the source as im struggling to work out the cause

 

[catlad]

Possibly the new felt too long in the gutter and humming in the wind.

Retrofit Eaves roll ventilation you can cut it and staplegun it in then fill the bottom of the soffit with acoustic insulation. Noise will disappear!!

would start by sealing the window.

Poorly applied or zero seals around a window, make an astonishing difference regards noise. I have been on the inside of a recently fitted window being (silicone) sealed, whilst working fellas were making a noise outside. When he applied the last long run of silicone, the difference in noise abatement was incredible.

See above. There could be other factors like they may have left holes in the previous soffits etc. It will be down to poor or inconsiderate fitting.
