Birds in the vent.
Chirping behind a bathroom fan, a dryer that has stopped drying, nesting material packed into a soffit gap. We clear it, then fit a guard over the opening so the same cavity is not back in use next spring.

Where birds cause trouble
Birds are rarely a problem because they are birds. They are a problem because of where they choose to nest, and the three favourites are all openings in the building envelope that were never meant to be nest sites.
- Dryer vents — the classic. Warm, sheltered, and the flap props open easily. A blocked dryer line is a fire risk, not just an inconvenience
- Bathroom and kitchen exhaust vents — chirping behind the fan, and a fan that has become noticeably less effective
- Gable and soffit vents — a torn or missing screen is a direct route into the attic
- Soffit and fascia gaps — nesting material packed into a gap beneath a fascia board, usually visible from the ground once you know to look
- Chimneys — uncapped flues, and everything that follows from that
- Droppings streaking a wall below a vent termination, or debris in the gutter below one
Not sure whether it is birds or something else? The clock helps — birds are active in daylight and quiet overnight. Work through the signs or call and describe it.
Why timing matters
An active nest is not always a thing we are allowed to move.
This is the part that separates a considered job from a fast one. Most native birds in Virginia are federally protected, and that protection covers an active nest — so what we can do, and when, depends on the species and on whether there are eggs or young in it.
In practice that means one of two conversations. Either the nest is inactive or the species is not protected, and we clear and guard it straight away; or it is active and protected, in which case we tell you plainly what the constraint is, make the situation safe where we can, and schedule the permanent work for when it is lawful to do it.
It is the same principle that governs our bat work, where the timing is dictated by the maternity season rather than by the calendar you would prefer. Being straight about it up front is better than discovering it halfway through.
What the mess does while it sits there
Nesting material in a duct is a blockage, and in a dryer line specifically it is a fire risk that gets worse every load. In an attic, accumulated droppings and old nest material hold moisture against timber and work their way into insulation. Where it has reached that stage, clearing and decontamination is its own piece of work.
How we handle it
We find out what is in there before anything is opened
Species, whether the nest is active, and whether the vent it is in still does its job. That determines both what is legal and what the repair needs to be.
Clear the cavity properly
Which means getting the material out of the duct rather than pushing it further along it, and checking that the vent moves air again afterwards. A cleared dryer line that still does not vent has not been cleared.
Then guard the opening
Vent guards and bird barrier are fabricated and fitted by us, sized to the vent so the airflow is not restricted. Gable vents get steel mesh behind the louvres; soffit and fascia gaps get closed as ordinary carpentry, because that is the other half of what Mike does.
Exclusion work carries a 1-year warranty unless we have discussed otherwise.
Bird questions we get asked
There's chirping in my bathroom vent.
Then something has nested in the duct, and the fan almost certainly is not moving much air any more. It is worth dealing with promptly — nesting material in a duct is both a blockage and, in a dryer line, a genuine fire risk. We open it up, clear it, and fit a guard so the next bird cannot use it.
Can you just take the nest out today?
Sometimes, and sometimes not, and the difference is legal rather than practical. Most native birds are federally protected, and that protection extends to an active nest — which means the timing of the work depends on the species and on whether there are eggs or young in it. We will tell you which situation you are in when we look, and what it means for scheduling.
What's the difference between this and a vent guard?
The vent guard is the part that lasts. Clearing a nest solves today; a guard over the vent termination is what stops the same cavity being used again next spring. We fabricate and fit them in stainless or galvanised to suit the vent, and they are sized so the vent still moves the air it is supposed to.
Birds keep getting into the gable vent.
A gable vent with a failed or missing screen is an open door into the attic, and birds are usually not the only thing using it. That is a straightforward exclusion repair — steel mesh behind the louvres, fitted so it does not restrict the airflow the vent exists to provide.
Is the mess actually a problem?
Droppings and old nesting material accumulate, hold moisture against whatever they are sitting on, and attract insects. In an attic it also ends up in the insulation. Where it has gone that far, clearing and decontamination is a separate piece of work — see attic insulation removal.
Do you handle birds inside the living space?
Yes. A bird that has come down a chimney or through an open door is usually a matter of opening the right window and darkening the rest of the room, and we are happy to talk you through that on the phone before anyone drives anywhere. If that does not work, we will come out.
