Mrs. Lee, who lives in the siancai river, has recently had a headache. As soon as there was a wind, the window of the bedroom sewped and poured into the house, and the sound of a “swool” was heard at night and a small ash fell on the window table. She was going to spend thousands of years changing new windows, and the master came to the door and looked at them: the seals of the doors and windows were ageing — the glue was tanned for seven or eight years, and it was broken, and it wasn't pressed. Changed a new tape, done one afternoon, at less than $200。
In xi'an, this leaking of doors and windows is so common. This side of the north-west is tanned and cold in winter and summer, and seals are the fastest-depleted parts on doors and windows. Many times you think the window's "life-long" and you can actually save it with a glue。
Why are the windows leaking? Nine out of ten were seals
The seal is the soft tape between the window window window and the window frame, covering the wind, ash and soundproofing. In the long run, these aging manifestations will occur:
(a) cracking of the tape: the hand is frowned, the surface is frazzled and elastic
(a) declining: the tape is shrunk out of the carton, the edge is sewn
(a) fluffy fowl: the fur on the lashing window is sealed like the fur, which is prolonged in the fowl, falls out of the hair, and cannot withstand the wind
Scrambling age: when the glue in the glass is hardened, the sense of stitching closes the window。
Of course, leaks can also be caused by loosely bound pages, deformed windows and loose locks, but, empirically, seals are the most ageing. The way to judge is simple: close the window and put a note in the sew, and then slit it off, which means that the seal is basically dead。
How much for a seal? Xian reference line
The price is mainly window-type and glue-coated material, which gives you an approximate range (including manual, which is the basis for the above-mentioned door test quotation):
Item
Reference price
Push-and-pull
3-8 yuan/m, approximately $30-80 per window
A flat window of $3 bc glue
8-20 yuan/m, about $60-150 per window
Aluminum broken doors and windows with stripes
It's complicated, about $150-300
Change the seal for the whole window
Approximately $300-800 by number of windows and metres fine
Several factors affect prices: first, floors, high-level work is difficult and costs are slightly higher; second, window-types, old steel windows and exotic windows are more expensive and expensive; and third, materials, three dollars acetylene, is more expensive than normal glue, but can be spent more than five or six years。
These pits, avoid them first
Pit one: low-cost fishing, up the door. The quotation stated that the “dozens of full packages” were then said to be of a special window type and had to be completed, and the cost had increased several times. Remember: the formal approach must be to test, offer, you confirm and then start without an offer。
Pit ii: fill it with a second. It's three dollars bc with bad regenerative glue. It smells of stingy nose, it's got a hard hand, it's getting old in a year or two. Before doing so, you can have the master tear a little bit of it in front of you。
Pipe three: no bail, no one takes care of the problem. When the seal was filled, it was not seen to be wrong, and it was not until two months before the shrunk out of the slot that it was not available. A quality certificate is given for a reliable service, with a clear statement of the duration of the warranty。
Formal maintenance channels, such as simple-to-home lines, implement standards for services such as first-in-first-in-time pricing and 90-day quality assurance, offer a single price at the meter standard, and avoid price-in-sitting after work, which is relatively less expensive for families who are not familiar with the business。
Who's on the other side
(b) underline individual maintenance workers: flexible prices and high rates of activity, but the skills vary widely, with people leaving and selling largely dependent on fate
(a) physical maintenance of doors: the material is relatively secure, although the range of services is mostly in the vicinity of the stores, and scheduling depends on luck
Online formal maintenance channels: priced code, processable, quality warranty, suitable for the family of a working parent or a local teacher with no acquaintance, and wait for the order。
In conclusion, the windows and doors of the sian leak, so don't rush to change the windows and check the seals at a small cost. The price was clearly asked before the action was taken, the offer was confirmed and the certificate was kept in good quality, and there was little room for stepping。
Common problems
Q: can you change the seal yourself? It is simple to pull a window, and can be done with a great deal of power; but it is not easy to break glass bars with a flat window and broken aluminium. It is recommended to the professional teacher。
Q: how often do seals change? The normal tape is used for three to five years, and the three bcp materials are used for more than five or six years, depending on the sun and usage。
Q: what happens when you change the tape? It would not be a matter of sealing, focusing on whether pages, locks and windows had been deformed, so that masters could do a quick check and not repeat the costs。
