Hello We are currently renovating our house. Its pretty old and we have done all the work ourselves to save on costs. However we Hi there, I have recently moved into a house with a beautiful wood burning stove in the living room.
However the people who Hi we want to unblock a fireplace in the front room of a house we've moved into. With a chimney, half of it is exposed to indoor temperatures and half to outdoor temperatures.
With a blocked fireplace and sealed chimney, these different temperatures frequently cause the moisture in the trapped air to condense, become a liquid on the inside surfaces of the chimney. As more air leaks in so does more moisture. A blocked chimney will actually allow more water into the home than it did before it was closed off.
This will lead to odor, mold and water damage issues. Seasons temperature changes and weather conditions can damage chimneys in ways you may not expect! Sealing off a fireplace and chimney always collects water inside the flue. Plain and simple, DO NOT seal off a chimney or fireplace because you will get a flue full of condensation problems!
But these problems are only hidden for so long! We promise there are better ways than blocking or sealing a chimney and fireplace. Sealing off a fireplace always collects water inside the flue. Cold air coming down the flue and out of the fireplace can make a living room unlivable. There are temporary solutions to cold air coming in and out of the chimney. Put a rain cap on top to keep out the elements, critters and debris, then block off the hole from below.
Also Know, how do I stop Draught coming down my chimney? You can use a chimney balloon. A chimney balloon is essentially a balloon that you inflate in your chimney that creates a snug fit, thereby preventing hot air escaping up out of the chimney or cold air dropping down it, helping to prevent draughts in your home. A: Unused flues should be capped at the top, to minimise rainwater ingress.
But it is important to maintain a flow of air through a redundant flue to prevent dampness problems in the chimney stack itself, the chimney breast where it passes through the loft space, and in the rooms below. If your chimney is blocked up and is capped and sealed at the top, the lack of ventilation could be causing chimney condensation to build up in the void, meaning that when your house warms up, condensation collects and forms damp on the chimney breast surface.
Install dampers at the top or throat of your chimney. Install chimney balloons at the throat of your chimney. Seal the chimney with a tight-fitting screen. Step 1: Safety first. Step 2: Check your chimney. Step 3: Install a damper or balloon. How can I tell if my chimney is capped? It prevents draughts and moisture but still allows the chimney to breathe. Follow the measuring instructions for the chimney balloon and order the appropriate size for your chimney.
When we removed our old back boiler, we were left with a gaping hole that looked unsightly and let cold air into our home. We set about boxing it in so we could fit an electric log burner effect stove in the space left from the removal of the boiler. We secured some 2 x 1 around each of the 4 sides, just above the eyeline.
We then attached a piece of plywood to the underside of the 2 x1 and drilled 4 holes in the middle of the plywood. We screwed a vent over the holes to allow the chimney to breathe then placed the electric log burner in the hole.
On the outside we secured a piece of 4 x2 to the wall either side of the fireplace and screwed an 8 inch wide, 1 inch thick piece of wood along the length of the top. This was then undercoated, and painted white and now we have a wooden mantlepiece with a log burner inside. We never tackled this, our chimney has a vent on it that prevents birds and to a certain extent rain getting through. But if you have an open chimney with no vent it is favourable to get this blocked properly.
If you feel confident you can get up on the roof and have a go yourself or hire a professional. Be prepared for additional costs that might crop up like:. In the old days chimneys were capped using lead capping, but they can cause condensation, so now roofers use the C-Cap.
C-Caps prevent heat loss while still allowing ventilation.
