Soundproofing spray foam insulation in Devon is worth being straight about from the first line, because the word soundproofing promises more than any insulation can deliver. Foam does two things to sound: it absorbs it within a cavity, and it closes the air gaps sound was travelling through. It does not add mass, and mass is what actually blocks sound. Knowing which of those three mechanisms your problem needs is the whole decision.
What people in a quiet town are actually hearing
Devon is small and the background noise level is low, which makes individual sounds stand out in a way they would not in a city. The calls we get here are mostly internal rather than external: footsteps overhead in a storey-and-a-half house, a stairwell that carries every conversation to the bedrooms, a furnace or a sump in a basement that is now a family room, and the shared wall or floor of a basement suite. Outdoor sources are a smaller share — traffic on the highway corridor east of town, equipment on the county land, and wind along the valley.
That internal pattern is good news, because internal noise is the kind air sealing and absorption handle best.
Open-cell is the material for sound
Open-cell foam at roughly R-3.5 to R-3.8 per inch is soft and porous, and it is the better acoustic performer of the two. It fills a cavity completely and absorbs mid and high frequencies rather than reflecting them. Closed-cell is rigid and dense and is the wrong choice for an interior acoustic wall — it is the material for moisture and exterior work, which is a different brief.
Where it works and where it does not
It works on a cavity that was previously empty or loosely filled, and on gaps — around electrical boxes, at the top and bottom plates, where a duct or pipe crosses a wall, around the trimmer of a doorway. On an older Devon house those gaps are plentiful and they are a direct air path, which means a direct sound path.
It does not work on low frequency. Bass, footfall impact and a heavy vehicle are structure-borne and travel through the framing itself, and filling a cavity does very little to them. If footsteps from the storey above are the complaint, the answer involves decoupling the ceiling and adding mass, and foam is at best one layer of that assembly.
The honest order for a basement suite
Seal the penetrations between the two spaces. Fill the floor and partition cavities with open-cell. Then, if it is still not enough, add a layer of mass and resilient channel on the ceiling. Those steps get progressively more expensive and progressively more effective, and skipping to the last one without doing the first is money poorly spent.
A caution on doors
Where a room is being quietened, the door usually becomes the weakest element the moment the walls improve. A hollow-core door with a gap at the bottom will undo a well-built wall beside it. It is not our trade, but it belongs in the conversation.

Soundproofing Spray Foam Insulation Devon: Common Questions
Will foam stop footsteps from upstairs? Not on its own. Impact noise travels through the structure, and the fix is decoupling plus mass. Foam in the floor cavity is a partial contributor.
Which foam for sound? Open-cell. It is porous and absorbs; closed-cell is rigid and is the wrong material for an interior acoustic wall.
Will insulating help with outside noise? Some, by closing the air paths. But windows carry most of the sound into a room, and insulation cannot change that.
How much does soundproofing spray foam insulation cost in Devon? Priced per board foot of cavity filled, so the wall or ceiling area and depth set it. Whether the finish is already off is the biggest variable, because opening a wall costs more than filling it.
How do I choose a soundproofing contractor in Devon? Ask what will not get quieter. A contractor who tells you footfall needs more than foam is giving you the accurate answer.
